Split-Single Motorcycles !

In this video I will introduce you to 8 motorcycles powered by a two-stroke "split-single" engine. In the entire history of the motorcycle industry, only 8 manufacturers have used this type of engine : Garelli, Puch, DKW, EMC, TWN, Manet, IsoMoto and Csepel.
Many thanks to all bikers and motorcycle fans who contributed their videos to our motorcycle channel. If you have a motorcycle at home that you built yourself, or an old, interesting or unusual motorcycle that you would like to show, please send me short videos from your camera or mobile phone to: We Transfer - [e-mail]
I will process your videos and publish them on our motorcycle KZbin channel - Jawa Tino

thank you for that, I don't normally care for the sound of two strokes but that split single has an interesting exhaust sound, that Manet was beautiful

[@PRH123]

Manet was great looking, and love the simplicity, nothing that’s not needed

[@tonysargent1699]

Ahh, memories. When I was a kid, there was a guy lived up the road from us who owned a Puch split single. All week he would use use his Honda cd185 Benly for work, but on Saturday morning between 8 and 9 o'Clock, he would polish his bike in the garage with the door open, then, after got his riding gear on, he would start it up and ride off down the road on it and the sound of it would make me feel warm inside! So thankyou so much for bringing these amazing little machines back to us!

[@jan-hg9vi]

Fun fact. I live 25 mile east of Cincinnati Ohio. Between me and two of my neighbors we have eight 250 Twingles a mix of ALSTATES and PUCH and add to that the 50cc Sabre's and 175cc we have more than 20 Puch's. Thanks for the video history lesson.

[@peterkordziel7047]

Do you want to sell the 175? I am seventy four years old and would love to have another bike to ride around town, I am not a speculator just love the old two strokes

[@jezztech]

The Garelli sounded awesome.

[@Rudyikotyk]

Як завжди, цікаве відео! Дякую за працю! 👍👍👍

[@57dogsbody]

It was said that when the supercharged DKW was raced in The Isle of Man, it was so loud that it could be heard in Blackpool (in England)!!

[@BRI33NOR]

Interesting explanation of how the engine was built. Around the 1950/60 era Dr. Joe Erlich designed and built a semi successful split single racing 250 c.c. machine. The EMC PUCH. Was quite quick for it's time, not too reliable, was overshadowed by the arrival of the Japanese machines. But was an excellent effort by virtually a one man organisation. Any one got photos or details?

[@jmjrademakers]

The manet is very cute, because it's so simple. I have a D.K.W. from 1955. I like the smell of it.

[@thinkandrepent3175]

outstanding! this channel never ceases to deliver

[@zedfatka3321]

I got a couple of the puch twingles,,, but my favorite is my 57 TWN Cornet with a 200cc twingle

[@bradc32]

the exhaust sounds great

[@陳茂坤-l4t]

太棒了，比有些國家還老的稀有老機器腳踏車！……🤩🥰🤩

[@56ya]

excellent video and wonderful motorcycles shown.

[@gabrielleandreamicca796]

Las motos alemanas !!! Un sueño !!!

[@mikebrown5648]

It looks good sounds good I like that sound of that 2-stroke

[@MrCyphermonkey]

Was going to ask why it’s not an inline twin then saw the shared cylinder head and single plug at 03:43

[@ferenccsabatoth4886]

So many thanks for showing the Csepel too! They problem was the cooling. They are unique motorbikes here in Hungary too. Thank you very much for this video!

[@heinzhaupthaar5590]

Interesting. I would've expected them and the EMCs to have less problems with that. Because they made the smart choice to cool the exhaust piston by controlling the intake with it, instead of using the already well cooled transfer port piston for both.

[@maxpayne2574]

No narration I'd like to hear what advantage it was thought this design would have. Also a description of the early bikes that used it.

[@alternator7893]

Split single, twingle, splingle or spingle :-D, my favorite one is the one from the BMW Isetta cus I love mini cars.

[@juanstadlich2895]

Muchas gracias!!! Muy bueno

[@routmaster38]

A bit different but a chap I used to know had a Scott Squirrel that yoweld and since reminded me of those two stroke Tuk Tuks in Thailand!

[@MAL-Collector]

The manet m90 is really cool.

[@Goomer]

I love the sound

[@nswiss19751]

Unique design but they all seem gutless

[@jasonbrown7258]

I wonder how an expansion chamber would be on one of these.

[@IgnisMan]

Unique Engine design 👌😆😁

[@Bird111648]

I bought a punch in the 1967 it was a one-cylinder and I had hell out of that thing it kept messing up the two caps on top once for gas once for oil with a dipstick I didn’t know much about motorcycles I was super young but after buying one I would’ve never bought another one they were sold through sear and roebuck catalog store

[@johnmartin1114]

My brother had a Sears allstate (PUCH) back in the day he liked it but not as well as his Yamaha YAS 1C 125

[@trex9801]

thanks for the interesting video

[@creepingjesus5106]

Is that ISO the same company who made big luxury GT cars with massive American V8s, like the Griso and Rivolta?

[@montenlee5797]

Verry good

[@elyass.k.n5994]

Perfect 👍👍👍🌹

[@gustavgnoettgen]

They sound really different from others

[@gasolinaoleo2349]

Awesome!!!

[@didntpassananan6569]

Sometimes it’s not sounds like 2 stroke It sounds like four stroke

[@ทักษิณปัญญาเพียง]

สวัสดี ครับ 😍😍😍👍

[@antiq777]

#️⃣1️⃣🏍🎬

[@autoshotty]

They sound sluggish for a 2-stroke. Having more than a 180 degree powerstroke would it flatten it's torque and H.P. curve ? ? ? . . . No sure what the engineers were thinking on this one.

[@neorev01]

I think they were going for efficiency and simplicity. The two piston design changes the port timing overlap. Ive owned several and it smells and sounds like a two stroke but feels just like a four stroke. Has good torque and very linear power curve. Ive only owned the puch versions and they were very reliable and pleasant to ride

[@MoeLarrycurly1]

🏍️✌️🖖🍺😀😀

[@Minimalist11Guy]

Thank you for creating this fascinating video about the two-stroke split engines; they sounded wonderful. Also many of them did not smoke. We owe so much to people with imagination.

[@neliangelova7370]

[@Ganesh.krish0212]

Every time I am in awe of the machining skills and engineering of our forefathers, thank you for making me realise and appreciate these icons of motorcycling.

[@sparty94]

very cool vid. didn't know there was such an engine.

[@johncavar2914]

There is nothing sweeter than an internal combustion engine😉

[@RobertR1200rt]

I wasn't fimular with this configuration. I'm wondering what the negatives where. Would explain why there where so few examples. I really enjoy your stuff keep it coming. Thank you

[@harrytazzia4133]

So what’s the purpose? I would think that cooling where the cylinders are together would present a problem!

[@ErgonBill]

That Manet is cute AF.

[@marciomonteiro4332]

Muito obrigado pôr compartilhar esse vídeo com essas jóias .

[@BooXdk]

Nice video 👍 A have a couple of Puch "doppelkolben" and they are very different to a "normal" 2-stroke in torque and sound 🙂

[@Bikerbob59]

There was a bunch of these type bikes sold as Sears allstates here in Canada in the 50s and 60s still a few around.

[@CZ350tuner]

Once transverse porting became more common, after 1946, split singles offered no advantages, only disadvantages, in performance when compared to conventional 2 stroke singles, twins & tripples.

[@carloleinardi5695]

Ibis 65 and 75 moto rossi 125, Leprotto 160 and 200

[@CreatorCade]

If I had the machining skills I’d try to make a 4 cylinder 8 piston model for a little car.

[@carlosshiota8827]

Awesome vid!

[@stanislavt6376]

Beautiful!!!

[@ericalbert6954]

Merci beaucoup l'Ami !

[@vancemarin8022]

👍👍👍🇨🇦🇨🇦

[@johnhenke6475]

What was the problem they were trying to solve with this design?

[@markjohnson8260]

Asymmetric timing of intake vs. exhaust ports. Rotary valve is another way, I think better.
