Brilliantly clear and fascinating explanations, matched by equally brilliant graphics. Keep up the amazingly great work, and thank you!

[@RT22-pb2pp]

Ridden for 40 pus yrs does not make me an engineer LOL I got basic understanding of bikes and the physics of some bike things but riding gives good riding experience, I know a few things but not an engineer by any definition. 4 yrs of engineering would be better than a ton of riding experience but 4 yrs of engineering does not replace riding experience as far as riding goes. I do a lot of things and did and until I took a beginners racing class at a track by racers I did things and did not even understand why or how it worked it just did, but knowledge is definitely good. understanding how things like counter steering works and trail braking, and manual speed shifting works is cool. Not to mention how to load and unload suspension for corners and how to load tires. I was told just do not surprise the tire before making a direction or braking change and it worked but until race school did not fully understand the physics of it. Still not a physicist but basic grasp of what bike is doing in transitions, best rule is this smooth is fast. jerky motions slow you.

Hey! Daytona 675 owner here, although it sounds like the tripple would be a not so smooth engine it actually is one of the smoothest bikes I’ve ridden, vibrates a lot less than a few of my mates bikes. Sounds nicer stock than any other bike and honestly the power delivery after 4k makes it feel like it’s got a vtech engine in it, highly recommend any bikers to have a go on a triumph because the engine is amazing and their bikes amazing handling, 10/10 hit the spot for what I wanted in a sports bike

It's about the SOUND.. even my old '05 Daytona 955i airbox is designed so the rider can hear the throttle bodies induction noise . The airbox snorkels are turned backwards towards the rider.. Engine, exhaust sounds are a huge part of the experience .. Those who have ridden my Daytona even say wow, what a sound .. very clever marketing tool.. visceral experience ..not sure the T-plane has any performance advantage ...this was done waay back in 2014 with Smiths Racing IOMTT Daytona 675 .. changed the firing order. Gary Johnson won on the T-Plane 675 that year.. but that was that. Sure sounded great. Always a give & take .. I think it's the exhaust note which makes you 'feel' like it performs differently..

This guy is a natural. Well done!

[@YAMR1M]

The Petronas FP1 did use a 180 degree flat plane crank in some of their race bikes during their final season in WSBK. It was never homologated and yes it would have sounded different to the 120 degree but they were desperate for power during that last season and the other teams knew it would never be a title contender due to being a smaller capacity engine compared to the 1000cc 4 cylinder bikes being used after the change from 750cc 4 cylinder to 1000cc 4 cylinder. The petronas FP1 was never going to be a bike that got sold even though rumours that the full homologation numbers were not met, Petronas did actually build the number of bikes needed to homologate them for racing even though they never passed homologation for the road at the time. Riccardo engineering did run a number of them to try to homologate them but due to over heating of the rear facing cylinder heads and the issues the race bikes had with cylinders becoming oval due to massive heat behind the cylinders and colder air on the forward facing intake side Petronas decided it was too much of a risk for them to sell due to the liability claims they could face.. But they did use flat plane cranks in a number of bikes. How do I know?? I worked for the company that made them..

[@carlmayer691]

Copy and paste right off the www verbatim ...LOL Smiths tried that in 2014 IOMT Johnson's Daytona 675 ..he won...but that was a one-off engine which really had no performance advantage except for the sound LOL

[@YAMR1M]

@@carlmayer691 co[y and paste off WWW? The 180 degree flat plane crank has not been mentioned on the internet and was never spoken about even though other teams will have known from the sound. But the 180 degree crank was quite a bit lighter than the 120 degree cranks. I know because I worked at the company that made them. The 120 degree cranks would allow the bike to rev to about 13,000 rpm but in the end the lighter 180 degree crank engines were supposedly going to 15,000rpm and as they plugged a fresh engine in after every race the extra loads on the pistons and rods was a risk they were willing to take. So between race one and race two later that same day the engine would have been swapped. The FP1 had bigger issues than the crank, it was only 900cc not the 1000cc like the others and the reversed head was distorting the cylinders as the back of the engine was so hot with no air supply to remove the heat and the colder intake at the front would have a disparity from front to back that was enough to distort the engine during racing conditions. The flames when going into corners was them dumping extra fuel (and some oil getting past the rings) trying to cool the engine every chance they had.

Fantastic explanation of the balance challenges and the pros and cons with the different configurations. Regarding the Laverda triple, I have to point out that all the production 3 cylinder (3C) Laverdas had the 180 engine from the very early ´70s up until the 120 crank made it's appearance at around 1982. The Jota was simply one of the numerous models produced. The reason for going to 120 was not vibration but engine noise for the regulators. A 180 motor in the rubber mountings of the 120 frame is a vibration fix. The character of the 180s has ensured that there are many who have never strayed, they are a unique experience and that is a major factor for a great many motorcyclists.

[@EliteRock]

The 'flat plane', 180° Laverda triple was known for being better able to withstand race tuning than the 120°, a lot of racers continued using it long after the introduction of the latter. I think this was because the pressed-up crank was less prone to twisting its crank pins/webs out of alignment at high RPM and outputs with the 180° layout.

[@selbub]

In the early 80s I rode a 1200 Mirage TS which had a 180 degree crank. The vibration was terrible. It was also very heavy at 250kgs. The original Jota was also 180 but I test drove a newly released 120 which was fast and smooth. I didn’t buy it because I wanted a tourer not a cafe racer. The Mirage with a120 crank would have been a great motorcycle. .

[@EliteRock]

@@selbub I can imagine what the 1200 must be like, in theory at least as much vibration as a big (400) single, probably worse in fact. The RGS with its polypropylene bodywork and 120° crank was my dream bike back in the day (one of the most expensive bikes on sale at the time), might have suited your needs by the sound of it. Laverda always made their engines heavy (the twins were just as chunky), I think the idea may have been to 'mass damp' the vibration (which didn't really work). People convert the twins to 270° with some success.

Just commented after the brake video. I would absolutely love a master cylinder video to help understand how you can actually brake faster (and almost more importantly, more consistently). Some guys deleted the booster but install a larger master cylinder. Chasebays make great kits, especially their dual piston master cylinder with a 6:1 pedal ratio. Thanks for these video, Mark

[@CP110]

The smaller the bore diameter the higher the braking force, however the smaller the bore diameter the less fluid it can move within the same stroke. so when you remove the booster, and swap to dual masters, they are usually smaller diameter than the single boosted master. Some people like the feeling of stiffer pedal and go up in bore size regardless if its boosted or not, however it requires more pedal force to get the same clamp force at the caliper. you can offset that a bit by increasing the pedal ratio (if space constraints allow, and pedal wont be too high)

[@MyKharli]

You cannot brake harder than the tyre grip break point that all well maintained brakes without abs should easily obtain. I have never been on a motorcycle that more than two fingers are needed , stiff calipers, air , and pad/disc contamination are behind all crap braking imao.

[@andrewahern3730]

@@MyKharli that’s true, but I don’t think that’s the question. I think it’s more about braking feel and that will be ABS independent. It’s ultimately a hydraulic system, so changing pistons on either side should affect the mechanical advantage, same as changing the fulcrum on a level.

[@808bigisland]

Ran Lotus and AC without boosters. No prob on light cars with single piston calipers and small discs. Double the brake tube diameter and add heatsinks on the steel lines. 3x the amount of fluid scavenges heat from the pads very quickly. Avoid rubber hoses.

There's something about the exhaust note of engines with numbers of cylinders divisible by 3--3s, 6es, and 12s. There's kind of a 5th overtone in there that's lacking in twins and fours. It may have to do with the fact that there's a 3:2 ratio between the stroke and the firing interval--like 180/120 which in harmonics is a 5th overtone. It's a beautiful sound, I think.

Great video! These engines are very mis understood. However, there is characteristic I think you didn't gave enough prase. You did briefly touch on it, but as an owner of two triumph 3 cylinder bikes, I feel it wasn't represented enough. The power curves are incredible. The ability to have such low rpm power and high rpm power is a great combination for a rider. Usually you trade one for the other, but these engines are so useful and fun because of this. Having to choose a low-end or high-end power band can seem fun, but over time impractical nature feels like a unseasonable limitation.

Triumph and BSA developed the 750cc triple cylinder engine with 120 degree cranks in the 1960's as the Trident and Rocket lll and they were lovely engines bearing in mind the state-of-the-art in those days. The engines ran in perfect primary balance with plenty of torque but a unique sound when pushed hard. I owned a Triumph T150V Trident for more than 30 years - blew it up in '78, kept it as a basket-case then rebuilt it in about 2005 and regret getting rid of it now.

This video made me recall my first Honda twin. It had the same firing order as my dad's John Deere, 180 & 540 degrees as opposed to Triumph twins being 360 & 360 degrees. On the Honda & John Deere the crankpins were 180 degrees apart while on the Triumph both pistons were at TDC at the same time. This gave the Honda better balance while the Triumph offered a smoother power flow. As for the John Deere balance wouldn't have been a concern at 900rpm.

Nice example! Here's a little video on twins in case you're interested: kzbin.info/www/bejne/l2q9d413d8Z_mMk

The Deeres do shake. The only reason balance isn't much of an issue is that they're so heavy that engine balance isn't that significant.

Great explanations. Now all we need is for motorcycle reviewers to be honest about the vibration result. Side considerations are engine noise, not exhaust noise, and RPM at highway speeds/gearing. An example would be the BMW K100LT I used to own. It was comfortable at only one speed, 73mph, and buzzed everywhere else.

My Rocket 3 Storm is really smooth and has tons of torque and traction. GJ Triumph! again, great video. I learn so much from these.

In 1978, I bought a Laverda 1200 Mirage brand new, it definitely had a 180 degree crankshaft. Unusually, it was pressed together, with ball bearings for the main bearings and needle bearings for the big ends, like a 2-stroke. It was, in fact, quite smooth. I thought that it was smoother than my friend’s Kawasaki Z1, which had an annoying tingle, at high rpm. The Laverda had an uneven exhaust note, a bit like a 4 cylinder engine, firing only on 3 cylinders. I installed an open 3=>1 open racing pipe which could be heard from about 2 miles away . . . . it was a beast! In 1981, Laverda switched to a 120 degree crankshaft, which made a smoother sound, but lost the character of the original 180 crankshaft and it vibrated at high rpm.

Cool video. This makes me think of the 2.9L F154 V6 in the Alfa Romeo Giulia/Stelvio Quadrifoglio. I believe the firing order in that guy is 120-60-120-60-120-60. The sounds is astoundingly unique. Audi/Porsche have a 2.9L V6 as well, but they utilize offset journals to accommodate an even firing order. Lower RPM and nowhere near as fun to listen to.

I'm a big fan of these videos illustrating, by sight and sound, the difference throughout the rev range. I'll admit to being nearly obsessed over the different crank configurations of parallel twins.

[@AllTheRamenOnTheSky]

Very cool video. Normally stuff like this just goes well over my head, like even if you explained it like I'm 5 I probably still wouldn't get it, and yet I was able to comprehend most of this. I think the visual stuff helped a lot.

[@2minstomidnight]

Great explanation, thanks! Check out also the BENELLI 900 & 1130 engine 3 cilynders engine! Cheers!

1:39 Now if we take a circle, which is obviously 360 degrees, and divide that circle into three equal parts, we'll see that it turns into a Mercedes logo.

[@johnsimpson2096]

Brilliant video. Something aside from firing interval and balance is the inertial effect of the constantly oscillating piston on the rotation of the crank. Don't claim to be an expert on this but I believe that a 90 degree crank pin spacing cancels this out while 180 spacing reinforces it. I have not seen any of your videos refer to this. Could be one reason the cross plane engine is so good for racing because the crank rotation is smoother and better for tire wear and traction.

[@d4a]

You're speaking of secondary balance. Watch the graph and the 90 vs 180 crank offset will immediately make sense. Watch the linked video to learn why it actually happens.

[@llaughridge]

Thais was EXCEPTIONALLY well-presented and illustrated. 👍🏻

[@c.a.r.s.carsandrelevantspecs]

Thanks so much for sharing another awesome video! The color coding was especially helpful for clarity and quick understanding of concept. Nicely done, and very informative!

[@m3talc0re]

Sound and feel from an engine can mean a lot. Just look at how much we love our Harleys.

[@YouMotorcycle]

Uber picky motorcycle rider here. Just wanted to say great video 👍

[@sean8470]

love my RIII Roadster 2014 from triumph with that inline 3 cylinder engine- absolutely awesome engine!!!

[@baetech1982]

I knew I was right when I chose Triumph....lol, awesome explanation....
