This is my favourite era of GP racing. Simple technical rules that gave free reign to engineers to exert their imagination and push the limits of technology. While Honda was racing a 23,000rpm five cylinder four stroke, Yamaha fielded a 125 V4 two-stroke.

It's pretty impressive, at 34 HP with 125cc that would make my ZX-6R produce 173HP (significant improvement over it's stock California emission compliant 134HP). I'm still just amazed how close we get with fewer cylinders and mass produced CHEAP machines that reliably do 50k-100k miles while doing wheelies and very little maintenance. Could you imagine them trying to get 7,500 miles per oil change? They probably have to do a teardown by then! This is almost the exact bike engine I'm wanting to build for my other motorcycle, I was going to make an inline 4 100cc 2 stroke (slap 4x 25cc weedwhackers together), that way it sounds like I'm screaming down the road but without speeding lol!

@@shawnsatterlee6035 I'm not sure when I'll do the oil change, I've got an oil lab kit I'll have sent off at some point so I can see how much contaminants it has in it. That's really the only way to know for sure is to test it and see how many ppm of metals etc it tests at. My car I do every 2k miles, but I don't know how often you ACTUALLY need to change sportbike engine oil besides what it says in the manual. Its about $48 in oil alone (plus filter and time), then crank the oil filter to 13 ft*lb of torque (I have my own custom filter socket adaptor for my torque wrench) and its not that bad. So far with 1500 miles after first oil change the oil in the sight glass still looks pretty new (I'm using synthetic oils), but I prefer to do more maintenance than the manuals call for because I want things to last.

You can, it's just probably more than they wanted to spend. Also interestingly I've seen some carbon fiber designs that look awesome, though carbon fiber sucks in compression so I don't know how they are being successful without making duel connecting rod boxer engines. Modern technology we can 3d print titanium parts hollow, once I get my metal 3d printer I can do some cool engine designs and one of my bikes will surely be a rotary just like my car.
It's hard to imagine my life before Visio racer channel
So sad we won't see these bikes again my favourite era 1964 till 1968.
That’s some crazy numbers but possible with small engines.
The term MotoGP was not in use during the time covered by this excellent video. It only appeared near the end of the 20th century,
Great episode but.. What about Mike Hailwood, and the 6 cylinder Honda 250cc?
Gud vid 😍
Its shame people forgot all other brands that raced.. Brands from Czechoslovakia, England and many others European brand forgot in history bc Japanese bikes.. It would be nice if you made some day video about them, From what I know Jawa and CZ from Czechoslovakia raced as well and their engines were worthy of telling their story

So my hotrodded 1971 CB350 twin revving to 7K at highway speeds is just fine, then?

Жыл бұрын
Besides the CB350 having some terrible issues with it's oiling system (disintegrates with age, my dad's rebuild 2 of them for oil system failure), then it's not too bad for that engine I don't think. My bike runs 7k rpm just below 70 mph but it sounds happy at 14k to 15k rpm cruising around (will go up to 16k rpm at 152'ish mph, but it needs taller gearing to achieve max speed). Some engines though can't handle much, my last bike I had screaming at 10k rpm (redline is about 8,500 and I thought it had a limiter... It did not, and I found out the hard way). So depends on the engine. Most I've revved an engine to was 18-19k rpm on a 2 stroke grass trimmer engine going downhill at 42-43 mph (12k rpm roughly at 28 mph), so it was way over-sped, but I didn't see any cylinder or piston wear and everything looked fine. So keep them below redline, they may not last long at limit speeds but engines can be replaced.
Interested to know cam timing specs on an engine that revs to 23k and stalls at under 17k

I doubt that is easily attainable information if even possible. Besides, its not just the cam timing, but the engine inertia, flywheel and these things that make it unable to idle by itself

They still make the fireblade 1000 RRRRRRR double R (Arg! Me pirate edition!). It's still one of the fastest production bikes that's road legal. They are also known for dependability, so that's not a bad reputation. He might be more impressed with Kawasaki pushing boundaries a bit more with things like supercharged production motorcycles, but emissions kind of ruin what you can achieve, they didn't have much emission regulation back then
Sorry. Not any research before asking my dumb question...but I'm surprised Japanese motorcycle companies wouldn't want Japanese riders who could probably be smaller and lighter..??

They did use Japanese riders, but the factories usually went for established riders from Europe and other countries as well. In the 1963 250 IOM TT Fumio Ito riding a works Yamaha twin came second to Jim Redman on a works Honda 4. But for a catastrophic pit stop of over 40 seconds, Ito would have won the race and become the first Japanese rider to win a TT.

The stroke is very short, same as the super high rev F1 engines back in the day, all HP and no torque. They have no practical application as an engine produced for the masses therefore the mfrs killed them.

Honda was genius!!! Todays prototypes are more ‘spec’ than ‘tech.’ Engineers have been hamstrung by limited rules. Especially the MotoGP class. Street cars are more advanced in many ways, with forced induction allowing for tiny but powerful engines. Wish they would allow more creative interpretations of the rules. Bring back direct-injection 2 strokes, and allow turbos and superchargers. Tiny but MIGHTY motorcycle engines are the future! We have the technical skills to ‘tame’ these beasts with modern digital tech.
