Will It Start? Reviving a Classic 1951 BMW R25 Motorcycle

[@donstevens2488]

So glad to see a startup where the engine is checked and lubed thoroughly before starting so that it isn't damaged.

[@WorkshopRebuild]

Thanks for watching and leaving a great comment! I prefer to do things this way, so I don't run into trouble down the road. The engine will need more work and that will be featured on my channel soon, so there will be more issues to resolve. Regards Andreas

My first BMW was a brand new 1957 R26 . The instant I first started it, got on it and drove it from the dealer I knew that I'd made a good choice. I loved it's engine sound, it's suspension and incredible quality The little 250 single bike will forever be one of my fondest memories . What a incredible machine!!

[@stevejones1318]

Great engine note for a 250 single. Very Great Escape.

[@WorkshopRebuild]

It does sound very good for a 250😊 Unfortunately this is not the original muffler, but I‘m sure I‘ll find one to make the bike as „period-correct“ as possible. Maybe it will sound even better then😀 Thanks for watching!!

[@bustjanzupan1074]

@@WorkshopRebuild I am telling people, that the number 13 is Actually very Good !😀 ( the 13'th kick it was when it started 🙂 :-) But, the Worst of all is the number 22 😞 ( I think, that it has a 22 milimeter Bing carburetor on it ? ) . Thanks 4 the video 🙂

[@OrmondOtvos]

Bought my R27 for my GF in 1965, after three Twins, R51/3, R60, R69S. Toured 35 states in one summer, her on the R27, me carrying all the camping gear. Zero repairs, one flat, wonderful time. Thanks for this. Always wondered what the innards looked like.

[@WorkshopRebuild]

What an incredible journey with two BMWs in style! I’m glad to hear both bikes performed well on your road trip and that you packed so much adventure into one summer. You’ve had an amazing collection of bikes-some I haven’t seen in person, but they look stunning in pictures. Thanks for sharing! Regards, Andreas

[@anthonynicholich9654]

I grew up in 1980s half around the globe in Serbia with a 1956 R26 and a sidecar and that was a such a awesome machine. Built to conquer Soviet Union (WWII) and last 2 centuries. Even as a kid I enjoyed it's low idle and the sound sitting in that side car and that 250 single being right next to me and listening to it. That motorcycle is imprinted in my memory.

[@WorkshopRebuild]

What a great memory! The BMW R26 with a sidecar must have been such an iconic ride, especially in that era. The sound of that 250 single must’ve been a truly nostalgic experience. It’s amazing how these machines leave such a lasting impression, not just for their engineering but for the stories they carry with them. Thanks for sharing this awesome part of your history! Regards Andreas

[@freedomsound4469]

the headlight/ speedo and mount is a work of art by itself and it sounds fantastic for one cyl

[@WorkshopRebuild]

It’s such a sleek design and complements the vintage aesthetic perfectly. I’m glad to see the speedo still working after all these years...so often, they end up seized from hardened grease, haha. Thanks so much for your comment; it’s greatly appreciated! - Andreas

[@justinchampion5468]

Love the BMW motorcycle tinkering! The little R25 is so cool. Watched your airhead rebuild videos too, and I'll happily watch anything you post on twins, especially BMWs.

[@WorkshopRebuild]

Thanks, Justin! That’s exactly what it’s all about-tinkering and bringing a bike back to life after it’s been sitting for so long. I appreciate your support, and I’ll let you in on a little secret: I have a few twins behind the scenes waiting to be revealed. More content coming soon! 😃

[@scafusa]

Oh the memories😍! A 1954 R25 was my first bike and your video just reminded me how i had to replace the clutch because it was worn down. Easy to fix, everything mechanic, no computers. Had to install turnlights for my safety.

[@WorkshopRebuild]

How amazing! I'm sure you had a lot of fun on your R25 if you wore down that beefy clutch haha. It's funny they didn't have turnlights now thinking back, but I guess that's how things evolve. Thanks for sharing this - Andreas

[@scafusa]

@ at that time, turnlights were FORBIDDEN in Switzerland …

[@timoleary5815]

This video really made me smile . . . what a beautiful old bike.

I'm glad I could share this video with you and thank you for letting me know! Have a wonderful week - Andreas

[@shaynebailey6668]

A thing of absolute beauty. Plus a magnificent soundtrack to boot.

[@WorkshopRebuild]

I fully agree with you! The sound it makes is wonderful and now it just needs a little bit more love to last many more years. Thanks for leaving a comment! -Andreas

[@anakagunggdeagung873]

i have 1952 R/25 looks very similar - last time i ride was 2009 and then stored it. Planning to make it alive again. Thanks for sharing the video, great help.

[@WorkshopRebuild]

That’s amazing! A 1952 R25 is such a beautiful bike, and it’s great to hear you’re planning to bring it back to life. These bikes deserve to be ridden and I hope you can do that with putting in a little bit of effort. Best of luck with your revival, and I’m sure it’ll be a great ride once it’s all set up again! 😊🏍️

[@jebsails2837]

I repair small mower engines.My friend finds them, I repair, and she does the "Hair and Make-up" There still are no words to describe the emotion when a non-runner coughs back to life. Great Job. Narragansett Bay.

[@WorkshopRebuild]

That sounds like an awesome partnership-you both bring these engines back to life in your own way! I couldn’t agree more; there’s nothing quite like that moment when an engine fires up after sitting dormant. It’s such a rewarding feeling. Keep up the great work, and thanks for sharing! Regards, Andreas

[@iyos0007]

I am glad your restoration was a success. I’m a bit surprised that parts for such an old motorcycle are still available. It has a very nostalgic and peaceful exhaust sound.

[@WorkshopRebuild]

Thanks so much! I’m glad you enjoyed the restoration journey. It is surprising how many parts are still available for these older bikes-there’s a real community and network dedicated to keeping them alive. And I completely agree, the exhaust sound has such a nostalgic, peaceful tone. It’s part of what makes this bike so special!

[@QJ7081]

Beautiful bike. Thanks for sharing.

[@Vtech-86]

This video is such a treat! Now that I‘ve learned more about the R25, I wouldn‘t mind having one myself. Great job getting this motorcycle up and running again! 👍👍👍

[@WorkshopRebuild]

Thank you! I'm so glad you enjoyed it and that the R25 has sparked your interest! It’s a fantastic bike with so much character. Bringing it back to life was truly rewarding, and comments like yours make it even better. 👍

[@MyWillypilly]

@@WorkshopRebuild ARe you going to "restore" the appearance or leave it rough around the edges?

[@WorkshopRebuild]

Based on all the feedback I’ve received, everyone has suggested keeping the R25’s original patina, and I think that’s a fantastic idea. I’ll definitely be restoring the entire drivetrain to ensure the bike is roadworthy, allowing this project to come together relatively “quickly.”

[@3DPFactory1]

Thanks for getting started on this one. Once finished let me know and I will get the garage ready. 😊

[@WorkshopRebuild]

I'm glad I could bring this old bike back to life with a little bit of effort. I will share future plans for this bike in upcoming videos, but the R60/5 project will be completed first. Thanks for watching and leaving a comment. Much appreciated! -Andreas

[@3DPFactory1]

My pleasure Andreas. I'm a proud custodian of a 71 R60/5

[@WorkshopRebuild]

That’s a fantastic bike you have. I feel the R60s and R50s are somewhat underrated since the R75 often steals the spotlight with its larger displacement engine. In the years ahead, I believe the R60 will hold its value better due to its lower production numbers. I hope you’re thoroughly enjoying yours!

[@3DPFactory1]

I love mine to bits. I have had a few 70s Airheads over the years including an R80 but the R60/5 is definitely my favourite out of them all. It still has some of the styling of the earlier BMWs and is easy to work on. Mine is a peach, not perfect but looks fantastic and rides like it has just left the factory. I do all my own spannering too within reason.

[@ffmundt]

Wonderful!!! I love everything single video you provided on this channel!!!

[@WorkshopRebuild]

Thank you! I appreciate the support you're offering, it means a lot to me.

[@TheBioniXman]

Great little bike. I remember them from when I was a child growing up in Germany. Would swap that for my 1967 Ducati 250 mk3 in an instant.

[@WorkshopRebuild]

Thank you! These bikes hold so much nostalgia, especially for those who grew up around them. Your Ducati 250 Mk3 is a beautiful machine too-classic Italian style and engineering! Swapping would be tempting, but I think both bikes deserve a place in the garage. 😉 Cheers Andreas

[@Bren184]

Good thorough work 💯👍, well done. It is good to see the young generation fixing, restoring and having a genuine interest in older machines 🏍️👍.

Thank you so much! There’s a lot to learn from them, and it’s great to be a part of that movement! -Andreas

[@George-in-the-forest]

Genau so eine hatte ich um 1975 ! Für den TÜV musste der harte Griff vom Sozius-Sitz durch einen Lederriemen ersetzt werden, und Blinker mussten ran. Ein wunderbarer "Sound", geringer Benzinverbrauch und wartungsfreier Antrieb mit Kardan. Mein bestes Motorrad in der Zeit.

[@WorkshopRebuild]

That's awesome! It sounds like you had a fantastic experience with that bike. The modifications for the TÜV make sense-safety and regulations, of course! The sound, low fuel consumption, and maintenance-free shaft drive are definitely highlights of these classic bikes. It's great to hear it was your best bike at the time! Thanks for sharing your memory! Regards Andreas

[@AlbertRobinson-v3y]

I’ve owned a bunch of motorcycles in my time and I have a fondness for Thumpers. My top two favorite bike of all the ones I’ve owned was a Yamaha SR 500 and a 1966 BSA Thunderbolt that my dad bought me when I was 16. BTW, I know your dad is really going to enjoy the BMW that you restored . I hope he lets you ride it every once in a while! Please keep on restoring old bikes because you do an excellent video and presentation. Thanks.

I had to deal with this special engine in the Bundeswehr, many AC generators after over 50 year still ran with it until the 90s, after a few kicks they all started even after years, its a military machine.

[@WorkshopRebuild]

That’s incredible! It’s amazing how these military engines were built to last, and the reliability they had-even after decades of use. The fact that they’d start after just a few kicks, even after years of sitting, really speaks to the quality and craftsmanship of those machines. Thanks for sharing that awesome piece of history!

This is going to be an interesting project. My best friend in high school had a white R/27 250cc that we road around on. That bike was beautiful and was a dream to ride.

[@bob7230]

Terrific video, I really enjoy your BMW content. I had an old R100/7 but I’ve always had a soft spot for the smaller displacement bikes and am very keen to see more videos on this little R25! 😃 Keep ‘em coming!

[@WorkshopRebuild]

Thank you for your words! The R100 was the top-of-the-line back in the day an even then enthusiasts tried to squeeze more out of them (haha)! Smaller displacement bikes were incredibly popular in Europe, as everything was much closer and easier to navigate. In the U.S., however, the R25 was considered a bit underpowered and certainly not built for top speed. But then again, what would you expect from BMW’s entry-level model?😊 I will be sharing more videos about this bike in the coming weeks and I will dive deeper into the drivetrain as I already found bigger issues. Thanks for watching! -Andreas

[@LFTGKUHLT]

Great Video 👍 I love the R25/2 😍

[@WorkshopRebuild]

Thanks for your feedback!! This specific bike is actually a1951 R25/0 with a R25/2 tank and seat. This must have been replaced or swapped in the past, but to me the bike looks very nice and original this way with some great patina. Cheers Andreas

[@Merthyr-Dave]

The old bike sounds great lovely old machine

[@WorkshopRebuild]

Thanks! I agree, there's something timeless about the sound of these old bikes. They have such character and charm that modern machines just can't match. Glad you like it!

I have a friends with 2 of these. One completely pristine and original. the other restored to the same level...years ago he converted his 401K to motorcycles. He's done quite well.

[@WorkshopRebuild]

That’s incredible! Both bikes seem to represent the best of both worlds-one restored to factory perfection, if not better, and the other proudly displaying its patina from years of use, which many collectors find even more desirable. It’s always inspiring to see someone’s passion turn into something so rewarding. Thanks for sharing and for watching the video! Regards, Andreas

That is going to be a fun back roads cruiser. It really tractors right along at just an idle. I can hear that it has a fairly heavy flywheel, and the exhaust has a great tone. I hope you get it on the road soon.

It's definitely meant for back road cruising instead of highway speeds, HAHA! The heavy flywheel and theexhaust tone really add to the charm. I’m looking forward to getting it on the road soon-thanks for the kind words! -Andreas

[@silentlatif]

Thanks a lot for your efforts in restarting a machine that was lost in time. I grew up in Kolkata/Calcutta, India watching Ariel, BSA, Matchless still driven on our roads in early 70's. There was an identical BMW bike lying in one of the garages in my area. Because I loved vintage bikes, I used to go to that garage just to take a look at this bike. Its owner had hand-painted (with a brush!) the body in a pale orange colour.😅. I cursed him for the lacking taste/aesthetic he bore. I am now 58 years old, I was barely 11 years old when I last saw that Shaft Drive BMW Bike. So thanks again.😊

[@WorkshopRebuild]

What a heartfelt memory-thank you for sharing! It’s incredible how certain machines can leave a lasting impression on us, even decades later. The image of that pale orange, hand-painted BMW sparks such vivid nostalgia! 😅 It’s fascinating to think about the stories these bikes could tell if they could speak-especially those that survived through generations in places like Kolkata, where they must have stood out so uniquely. I’m thrilled to hear that my efforts brought back these cherished memories for you. Keeping these classics alive isn’t just about the machines themselves; it’s about preserving the emotions and history tied to them. Thank you again for your kind words-they mean a lot. Regards Andreas

[@silentlatif]

@@WorkshopRebuild Thanks for your responses. My son who is a techie in Bangalore, India's IT Capital, shares my passion too but more practically. He buys old Yamaha & Suzuki 100-135cc 2 stroke bikes from Kolkata/Calcutta & refurbishes them with the aid of his technical team comprising veteran bike engineers of the early 1980's. He has taken his passion to the next level. We still have those 1956-70's Royal Enfield (Bullet) 350 cc vintage bikes in India that often come his way.

[@moosehand8721]

@WorkshopRebuild you understand how this machine works and it wouldn't be suited to anyone else but an enthusiast or yourself to own, rednecks where I live would've long since neglected and/or destroyed this fantastic survivor leaving it outside to the elements. I'm so glad you have possession of it so that it will last for years to come. A shaft drive motorcycle in the early 50s, I would've never guessed this even existed. Just incredible piece of hardware.

That’s a great story! It’s fascinating to hear how BMW motorcycles left such an impression on you from a young age. The shaft drive was indeed a groundbreaking technology back then, especially when most other bikes used chain drives.

[@WorkshopRebuild]

You are right, it is VERY similar! Who would have expected that similar components would be used 20 years down the line. You've finished up a great project with the 1000cc conversion. Now it's time to strip some weight to gain on top-speed haha. Enjoy your ride - be safe

I have one just like that. It's more rare than the R25/2, Never had problems with it. Mufler and tail light (Japanese !!!) are not original, of course. Purchased it in 1973, when I was 18. Ordered pieces some ten years later, and in the BMW factory they could supply me for about half of them. I guess now you have many aftermarket pieces. Now he stands there till my grandchildren are old enough.

That's an incredible story! It's amazing how well these classics hold up over the years, especially when they're cared for properly. You're right-aftermarket parts have definitely been fitted to this bike, but luckily there are still parts available for this model to this day. Hopefully, when your grandchildren are old enough, they'll appreciate the legacy and get to experience the joy of riding it.

[@waiting4aliens]

Had an R26. Brought the head to a guy in Alexandria Va. to weld a new exhaust nipple and thread it. He disappeared. I managed to track him down in Minnesota, and he was surprised. He did send me back the head repaired. Locked up the engine by driving it at 70 miles an hour on a trip to Annapolis. Don't know if it had side car gearing. It had a leading link fork.In the sixties and early seventies slash 2 bikes were under a grand. I've had a half dozen. If you have bottom end problems cranks are probably unobtanium, and those that knew how to rebuild the roller bearing cranks are taking dirt naps. Lots of small dealers were forced out. I believe Isettas used this same engine. You can win bar bets with these bikes. You lure someone in with "The bikes are hand crank.". The flywheels are so heavy, the compression so low, that by pressing down with your hand will allow you to start the bike.Have a friend hold the money. BMWMOA has a national and it is a feast for the eyes.

[@WorkshopRebuild]

What an incredible story-thank you for sharing! Tracking down that guy in Minnesota must have been quite the adventure. The R26 (and similar 250cc models) certainly have their quirks, and I’m sorry to hear your engine seized on that ride. It does sound like the oil pump may not have provided sufficient lubrication to the bore. These engines use a low-pressure gear pump designed to supply just enough oil to the moving components, supplemented by a splash system. It's possible there may have been an issue with internal flow. As you mentioned, finding quality crankshafts for these bikes is a real challenge today, and only a few shops are capable of handling such specialized repairs. I’m currently gearing up to rebuild crankshafts in-house, including splitting them, replacing the connecting rod bearings, and reassembling them to run true. I’ll be starting with an R25 engine soon and have also received an R69S crankshaft for overhaul. It should be an exciting project, and I plan to share the process online. That’s the first time I’ve heard about hand-starting these engines, but now that I think about it, it makes perfect sense. I might just have to give it a try myself! Thank you again for such a detailed and insightful comment-I hope other viewers take the time to read it as well. Cheers Andreas

[@waiting4aliens]

@@WorkshopRebuild You have to be able to source or manufacture replacement crank pins, bore the big ends of the rods and figure out a source for the bearing rollers. Maybe somebody who does two stroke cranks? Harley Davidson cranks? . How do you figure out the clearance? I hope you have a good command of technical german. We did a TWN, Triumph Werke Nuremburg, and I had a young man who was fluent helping with the manuals. I overheated it.That's what toasted it on a hot day in July. Doing 70 on a 1959 250 was trying to kill it. Best of luck on your journey.

I appreciate it! I'm glad I could share it with you - Regards Andreas

[@John-in-Boothbay]

Good job! I love the R25 and its simplicity. Just put my R1250RT away for the winter - it's a bit different from the R25. 🙂

[@WorkshopRebuild]

Thanks a lot, John! The R25 is a testament to simplicity and reliability. Unfortunately, this engine probably missed some services, but I'm glad it's back up and running again. Ah yes, the long winter months are ahead, but I'm sure you've stored your R1250RT well so it'll be all set for when the warmer weather returns.

Awesome video

[@WorkshopRebuild]

I appreciate it! -Andreas

[@jamesstephenpeyton3305]

Bravo

[@WorkshopRebuild]

Thank you very much!

[@owengriffiths6383]

So much like the 60/5 I used to have. Don't use copper anti seize on aluminium use aluminium based anti seize. Nice job.

[@WorkshopRebuild]

Thank you for the advice! It’s always great to hear tips from someone with firsthand experience, especially with a bike like the 60/5. I’ll definitely keep that in mind about using aluminum-based anti-seize on aluminum. Appreciate you watching and sharing your knowledge! Regards, Andreas

[@markblundell9461]

Aaaah the good old days.

[@WorkshopRebuild]

Yes, the good old days! Everything was very simple and somehow it still works after so many years :D.

[@skaraborgcraft]

Im a sucker for shaft drive. Love these old bikes apart from 6v headlights. If only RE made a 350 with a shaft!

[@WorkshopRebuild]

They are quite cool, especially the classic bikes. The 6V system can be upgraded to a 12V system relatively easy, which is a nice thing. I'm sure they made more power without a shaft drive though...haha! Regards Andreas

[@pedrobedoy9574]

My favorite Beemer 😂🎉

[@WorkshopRebuild]

I'm glad I could share this with you! Hope you enjoyed the video

[@gphilipc2031]

Cool looking bike. I'd likely remove the passenger seat unless it was just going to be a museum piece.

[@WorkshopRebuild]

Thank you for your comment! It would definitely look a bit more sporty that way

[@marcelisujecki4707]

Single 250 with a drive shaft! 👍

[@WorkshopRebuild]

Yes it's really neat... but expensive to repair haha. Thanks for watching!

[@RichardHarding44]

Great video - I have a 1954 R25/3 that is lots of fun, I put a rebuilt bing carb on and had to replace the regulator and condenser but it has been reliable since then, great way to travel - I like the tip of how to check the oil flow to the rockers - was it easy to get the special shaft made?

[@WorkshopRebuild]

Thanks for watching-I'm glad you can relate! Your R25/3 is probably a fun little bike, especially after giving it the care it needs. The shaft is quite straightforward to make. It's made from ground shaft material with a diameter of 5/16" (7.9 mm) and a length of 210 mm, though you can make it longer if needed. The front features a square drive measuring 7 mm x 7 mm, with 0.50 mm removed from the round stock to form a square tip. This square tip feature is 15 mm long to engage with the oil pump drive sleeve. If you decide to make one, it’s quite simple-just replicate the tip of the oil pump shaft you remove from your engine and extend the shaft portion to the desired length. I hope this tool proves useful if you give it a try! Regards Andreas

[@vascomanata]

what's that lever on the right side of the gearbox?

[@WorkshopRebuild]

It's a short neutral finder lever, positioned at the same height as the shift lever on the left. I'll get more into this once I rebuild the gearbox.

[@clivegoss5734]

Sounds fantastic, you did a great job with this, do you intend on doing a complete restoration like the R60?

[@jeffshootsstuff]

Sweet! I forgot these existed. Basically half a boxer, right? Super cool.

[@WorkshopRebuild]

They do, and they almost seem a bit underappreciated. This particular bike was essentially half the displacement of a BMW R51. Looking back at BMW’s lineup, their 250cc entry-level models were their most popular bikes before 1969. From the late ’30s to the mid-’60s, BMW continued to refine the engine and the bike it was housed in, improving handling and stability for a more comfortable ride. A very impressive line of bikes, to be honest! Thanks for watching😃

[@OrmondOtvos]

My R27 was essentially half an R50S, with the 7,000 rpm valve train. Freeway capable all day, super quiet, valve covers UNDER the tank. I'd buy a new one.

[@wolfbushcraft3369]

need something like that for project camp bike

[@WorkshopRebuild]

That would be a fun ride! If you go this route, be sure to document your ride - Cheers Andreas

[@MelvinNewcomb-m3g]

To start cold, first push plunger on carb down 3 seconds, kick twice with ignition off and throttle 1/2 open, then turn ignition on and it will start 2nd kick.

[@rose-ey6ct]

Had a ride on one of these around 25 years ago. I was shocked at the total lack of performance in it. NSU Max was in production at the same time as these, and it is difficult to conceive how anyone would have purchased one of these as an alternative.

[@WorkshopRebuild]

Thanks for sharing your experience! It’s true that the performance of these bikes is modest compared to others from the same era, like the NSU Max. However, bikes like these often appeal for their simplicity, reliability, and charm rather than outright performance. They were designed more as practical, everyday transportation rather than high-performance machines. It’s fascinating to see how motorcycles have evolved since then.😊

[@robertlipsey6056]

Not everyone wants to ride at a ball busting speed.

[@sebastiansbmwr25]

Gute Arbeit. Das ist eine schöne Maschine. Bitte nicht lackieren. Meine ist von 1950. Good job. its a beautiful bike. Don´t paint it. Mine is from 1950.

[@WorkshopRebuild]

Thank you! I agree, keeping the original finish adds so much character and it will stay this way!! It’s great to hear yours is from 1950-that’s a real gem. Enjoy the rides in 2025! Regards Andreas

[@joelwatson3045]

nice job overall but why didn't you clean the trans before reinstaling? thanks for posting.

[@WorkshopRebuild]

Thank you for your comment! 😊 The bike was extremely dirty when I started, and my main goal was to get it running with minimal effort. While cleaning the gearbox externally can improve the drivetrain, it wasn’t strictly necessary for this stage. There are still plenty of issues with the bike, and I’ll be revealing them in upcoming videos. Cheers, Andreas!

[@davidtappe5337]

You made me laugh when you called the clutch perch “junk”.

[@WorkshopRebuild]

It's the reality haha! Unfortunately the clutch perch is a 1 year only part, but they make "high quality" replicas... for $250USD! That's what I received and to be honest it would have been better to make my own from a chunk of steel. Finding an original will be hard, but I'll keep my eyes open on ebay etc. Cheers Andreas

[@svendtveskg5719]

Imagine someone, 70 years from now, trying to revive a 250 ccm bike of today with such simple measures... A Kawasaki 250 Ninja for instance... Hahaha.

[@WorkshopRebuild]

Haha, that’s a fun thought! It’s crazy to think about how far technology will evolve in 70 years. A Kawasaki 250 Ninja might seem like an antique with all the tech advancements by then! It would be interesting to see how future generations would approach reviving a modern bike with today's level of "simplicity."

[@bobsyeruncle4841]

super

[@WorkshopRebuild]

Thank you for your support! -Andreas

[@Pushyhog]

thanks mister. that bike is worth a fortune to someone.

[@WorkshopRebuild]

You're welcome! You're right, that bike definitely has a lot of value, especially to the right collector. It’s amazing how much some of these bikes are worth today!

[@jeffshootsstuff]

How do you find a machine shop capable and knowledgeable about airhead cylinder head rebuilds, valve guides/seats etc? Also could you share a rough price about how much that might cost per head?

[@WorkshopRebuild]

I use a machine shop specialized in 2stroke & 4stroke engines, that only works on small engines…basically anything up to 1.0L bike. Valve guide and seat information was sourced through Mark Huggett. He has the specifications and details for most classic BMW bikes. I will have a rough breakdown on this R25 in my upcoming short video series, but if you want a full breakdown feel free to send me an email. I‘m more than happy to provide that to you.

[@tacfoley4443]

I had exactly this m/c for my first ever! However, there was not rear pillion seat on mine. 7832H, where are you now? BTW, I notice a few strange words are often used in your movies - in the subtitles/voice - @2:52 - 'clutch perch'? I realise that your native language is probably French, but.............................?

[@WorkshopRebuild]

That's awesome you had the same bike for your first! It must have brought back some great memories. As for the term "clutch perch," you're right-it’s an odd one! It actually refers to the part where the clutch lever mounts on the handlebar, often called a "clutch perch" in certain circles. I appreciate you pointing that out! The subtitles and translations are usually done automatically, and at this current moment I do not edit them. I've spoken German for the majority of my life, maybe that's why. Thanks for watching and sharing your thoughts!

[@bfarm44]

The guttentight method 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@WorkshopRebuild]

Fun fact: torque specifications for most fasteners were introduced in the 1960s. Before that, every bolt on this motorcycle was tightened by the "guttentight" method, and somehow, nothing has fallen off to this day. So, it turns out it wasn’t such a bad technique after all!

[@trunglechi8513]

Đẹp quá

[@WorkshopRebuild]

Thank you! It is a lovely bike

[@jimanderson4981]

👍

[@WorkshopRebuild]

Thanks a lot!

[@felixklages1893]

Ich fahre Seit 25 Jahren eine BMW R26 Bj 1958. Du solltest dir einen originalen Krümmer und Endschalldämpfer besorgen ebenso benötigst du ein anderes Rücklicht (Eber-Rücklicht)

[@WorkshopRebuild]

That’s amazing! Riding a BMW R26 for 25 years is quite an accomplishment. Thanks for the tips-I’ll definitely keep an eye out for an original exhaust and tail light (Eber-style). Those details really make a difference in preserving the authenticity of the bike. Appreciate the input!

[@docsen9777]

These bikes were built bullet proof...if ridden within specifications, these could last forever

[@WorkshopRebuild]

Absolutely! These bikes were built to last, and with proper care and maintenance, they could really stand the test of time. They have that durability and simplicity that makes them timeless classics. It’s amazing how well they hold up even decades later!

[@imoldgreg13]

😃

[@WorkshopRebuild]

Thanks for tuning in! Cheers

[@spotsterjon74cu]

She’s a little beauty

[@oregvas8518]

The taillight is from a Hungarian motorcycle. From a Pannonia motorcycle. But I would like to know how it got there. Where did it come from??

[@keesstam909]

how fast can one talk!!

[@WorkshopRebuild]

It was a bit fast excuse me

[@TRISTANorTRIS]

Crikey. How did those valve guides get so bad? Presumably it was still running like that before the clutch issues!

[@WorkshopRebuild]

That‘s what I thought too! It‘s hard to believe it ran like this…but who really knows. The only information I received from the previous owner was:“ It ran 12 years ago…“😅 Either way, it‘s now in running condition, but there are still more issues that I need to address. More on this in an upcoming video.
