Not just engine design, engineering in general. In the era of, say, 1960-1990, people just were more willing to think outside the box amd go wild (partially because of less strict safety/emmisions rules). A great example was NASA's X15, the fastest plane in history, which hit Mach 6 in 1967. Nothing today comes close to the top of the line stuff from that era, at least in terms of raw power/speed/brutality etc.
@@kg_canuck , agreed.. the world has gone soft these days, the glory days were much more unlimited and unrestricted- just look at F1, they are faster and safer etc. but it’s not the same as before.
I watch every single engine video you post. I really enjoy hearing engines that I otherwise would never have known about, and going into the history and the problems that were solved is even better.
Ernst Degner was not the mind behind the development of the two stroke. He just stole the work of Walter Kaaden. Kaaden was the real genius behind the development of the successful racing two stroke.
Correct. Kaaden used resonant exhaust systems invented by DKW designer Erich Wolf to scavenge two strokes. Prior to that two strokes used heavy deflector crowned pistons that could not withstand high speeds Kaaden also adopted designs developed by the independent engineer Daniel Zimmermann.
@Sohc_Vtec it is literally written everywhere on the internet. Just look fo Kaaden and you will find out about motorcycle racing before Japanese bikes were a thing.
Suzuki sucked until adopting their stuff, specifically rotary valves & tuned exhaust. They dominated after that. Iirc Suzuki got the 1st 5 finishing positions in the first major race after his help (the defector).
I love this stuff as I own a Motorhispania RX50 which is a 50cc mated to a 6 speed trans that makes 9hp and goes 70mph, it's on a bike that's considered a 9/10 scale crotch rocket and it appears full size but only weighs 200lbs. I also own a 1973 Suzuki TS185 2 stroke with the "Git Kit" that makes 25hp.
I own a motorhispania as well but it is the "furia" model that is more of an enduro style and has a 50cc am6 engine. The guality seems good because mine is a 2004 model and everything still works well.
it's amazing what can be achieved in a two stroke engine. I love these little engines myself and play with them all the time. even the nitro rc two strokes are fun. shame they have been all but forgotten in today's four stroke dominated market. maybe some videos on modern engines (if you haven't already done a video on them).
This tech was all stolen from Walter Kaaden, the engineer of MZ, where Ernst Degner came from. Walter Kaaden invented the rotary valve, figured out the expansion chambers on exhausts, and was the first to make a 200 hp/l 2 stroke. And all that in the span of five years. And then it got stolen by a traitor who fled the country and then raced for the competitor.
they are forgotten due to poor efficiency, fuel economy, and bad emissions. four stroke is superior in these regards. two stroke has higher rpm and wider power band.
There’s lubricant in the fuel, since the crankcase under the piston is used for fuel/air intake during the compression stroke, and fuel/air mixes with exhaust since both port/valves open at the end of the power stroke so the exhaust is “blown” out. A significant amount of fuel+oil goes out the exhaust.
I'm a Yamaha/Suzuki guy, Yamaha always seemed to "march to the beat of a different drum" than the other "big 4" and i like that, they also made the finest 2 stroke bikes (IMO) and their 4 stroke technology/engineering was always top notch. Suzuki was always a tad conservative in their designs, but again solid engineering with strong engines. I speak in the past tense because i lost interest in new bikes around 2010, and are mainly into restoring 80s 90s bikes and have managed to get a small collection going😀. 85 FZ750, 87 FZR1000, 94 TZR 250 SPR 3xv, 98 TRX850, 01 YZF R1, 86 GSX-R1100, 84 GSX-R400 gk71, and a single Kawasaki, an 84 KR250 (the tandem twin road bike, not a GP bike😄). On the "watch out for" list is a 87 Honda VFR750 in White, and a nice ZXR-750 preferably an 89 or 90 in Green! Theres no school like the old school.

Your english is way better than when i first watched your diesel 2 stroke vids nice keep it up share the un known gems with the world even i learn stuff from you thanks
As a recently turned motorcycle nut, this video is amazing... I learned about Enerst Degner from MotoGP journalists. So to see what he actually contributed to is pretty Cool. I'm off to geek out on the RP68🔥
I have 2013 Romet 717 4t. Unopened engine, just bogger jets, unlocked variator(so it can open fully) and CDI. It can get up to 80km/h, on stock engine displacement of 50cm^3. Pretty good considering 200km of range on ~4l of fuel.
when i was 17 i had a friend whose name was johann hummel and was austrian state champion in the 50 cc class, my 50cc moped at the time had sufficient 6.5 hp with which i was on the road in half of europe eg rome, athens but also in the giant mountains and up to trenčianske Teplice to visit my sick father
Hello!! As an long time subscriber and BMW enthusiast, owner of an M50 and M52 engine powered 3-series, i would appriciate an M50 or M52 episode, why it is such an great 6cil. Greetings from Czechia!!
Awesome, can you do a story about yamathi too? It is also about 50cc racing: a highly successful dutch racing team, manufacturing their own stuff for racing.
I understand 'stolen' makes for a nice headline. Yet it is incorrect. Suzuki got Degner and yes they made sure he came over, yet in those days many people escaped East Germany, that's why they build a wall in 1961... Stealing is illegal, what Suzuki did was not illegal, it was taking advantage of an opportunity. Which is what counts in business!
Those engines are just so ridiculos small and still so powerful. I knew that Honda and Suzuki were building these small engines, but really didnt understand how small engine parts would be... Amazing work from those engineers back then
Soichiro Honda HATED 2 strokes, would never let his company use or develop them, and was determined to beat them with 4 stroke technology, all Honda GP championship win were with 4 stroke bikes, thats why the NR 500 was developed. Rules for GP at the time stipulated 4 cylinders and 500cc were max allowed, so he built a 4 stroke 500cc V4 with oval bores 8 conrods and 32 valves that revved to 20,000rpm. It was a failure, but the tech was used in the NR750 road bike (more of a "look how clever we are" than anything else) and the NR750 TTF1 race bike. The TTF1 was quite good and showed promise but was VERY expensive, i saw it race in Australia and take its first win in the Swann International Series. 👍
I really don't understand why a lot more of these sorts of small-displacement motorcycles aren't way more popular because of their potentially low cost, particularly for amateur gear-heads on a budget, who like to race them.
Love the 2 stroke content. An episode on Penton/KTM? I have 2 with the engine that John Penton and Erich Trunkenpolz argued over and they are monsters!
I don't know how I missed this one, but I love pushing things beyond their limits, engineering extremes like this, it's awesome,. With the rotary valves why not supercharge the little engine? And with the single cylinder rules, why not build a supercharged dual acting engine,yeah it has two spark plugs , but only one cylinder, the supercharger, scavenger is required, but they would probably make a rule against a dual action cylinder, and an opposed piston would probably not cut it either, but supercharger! Boost would do it..
Suzuki basically stole mz design secrets. Degner was racing for mz which was a very small company but was starting to win races, Suzuki approached degner and offered him a ton of money to steal design secrets and race for them
No, they didn't! When Degner joined Suzuki, the Suzuki racers were already in their final form, and Degner merely provided assistance in the fine-tuning of the engines!
If memory serves me correctly (it often doesn’t these days) the later multi cylinder 250cc machines, Honda six cylinder and their like were engineered because the smaller the parts, pistons, valves etc were so small they created very little if any inertia unlike larger thus heavier parts.
you should look into modern 50cc racing cups like Freetech50. Nowadays with the same regulations (50cc 6 gears no variator) they achieve extreme horsepowers over 22hp very interesting to see how that's going on. I'm active in a dutch cup, 70cc air cooled two stroke. we achieve about 19hp nowadays, some are already above 20hp, with a puch moded engine....
Please make a video about two stroke 100cc go kart engines. They are masterpieces of the 90s karting reaching over 20k rpm. Also best drivers of f1 came to the sport from this karting class, like Lewis Hamilton and Michael Schumacher. I would love to see you make a video about that. :)
20,000 rpm's from an aluminum cased 50cc, 18 horsepower engine produced in the 1960's without the aid of computerized design or equipment. The engineers of that era must of been absolutely brilliant to have pulled that off!
Can you track the development of the 2006 limited Yaris. That motor was ranked best new engine of the year. Super executions of both timing and cam profile.
16 gears? That's some Fast and Furious shit right there! 🤣
There never were "16 gears". The most a racing engine ever had was 14, on the Suzuki 50cc RK67. The RP68 3-cylinder used the same gear set.
14
@@wojack7066 They used a kill button and no clutch to change gears very quickly.
@@RC116 The single cylinder 50cc Kriedler of 1964 had an 18 speed gear box.
No motorcycle EVER had a "16-gear" gearbox. Please inform yourself and don't believe the crapola posted here by ignorants.
