This shows just how clever and how highly skilled those Japanese engineers were. They moved motorcycle and engine design so far forward in such a short space of time, amazing.

[@danruble1894]

Honda took awhile to get into the F! game.. after a few years of limited success in the 1960's they backed away to concentrate on the young and quickly growing automobile market. which you must admit., they did quite well.. Coming back into F1 in the turbo era with Spirit, few gave any trust in their abilities to field a competitive operation... Anybody that witnessed the steamroller Honda GP bike program had an inkling... anyone familiar with Honda's F1 race foray in the eighties can attest to their total and utter domination of the series... All the other players knew that the Turbo Era was drawing to a close, so revamped their 4 bar machines to the newer mandated 2.5 bar rules.. Honda decided to build a WHOLE NEW engine/ car/ turbo program...Absolutely caught the troops flat footed and DESTROYED the opposition...They made a misstep in their last attempt,... they have something to prove...Honda will be on top again... It is only a matter of time.

[@g.stephens263]

I'm not a big Honda fan, but you have to admire their technological advances and engineering in their racing bikes in the 60's and 70's. Although not very successful, the V-4 500 cc engine with OVAL cylinders is a fine example. "Honda returned to the 500 cc class of the World Motorcycle Grand Prix series in 1979, following a twelve-year hiatus. The machine they had developed for their comeback - an entry in the World Grand Prix's most prominent class - was the NR500, powered by a four-stroke, DOHC V-four engine. With its oval piston engine incorporating eight valves and two connecting rods per cylinder, plus an aluminum semi-monococque frame complete with an inverted front fork, the machine surprised everyone with its daringly innovative technologies."

[@joepkortekaas8813]

It didn't surprise me: I predicted this design in an article in the Dutch magazine "Motor" (No. 8, February 1979, page 434). I predicted a stroke of 35.7 mm - the Honda stroke was 36 mm, I was 0.3 mm off!

[@PeterDad60]

Good for the track! My first motorcycle was an Honda S65 (65cc) 4 stroke single cylinder that could do about 57-58 mph in stock form. I learned a lot on that bike. I even motocrossed with it. Remember this was in 1965/66. My current favorite is my 2015 Harley-Davidson FLHP Road King Police. I like to ride on back roads with no traffic at speeds up to 25/35 mph. A complete turn around from when I was young. My 1976 Triumph T140V Bonneville 750cc won against all street motorcycles for 10 consecutive years from January 10th 1977 to Aug 1986 when I stopped riding to get married. That list included Honda 650 and 750 4 cyl's and Kawasaki 500cc 2 stroke and 750cc two stroke triples and GPZ 550, 650, 750 and KZ900 and KZ 1000cc 4 cyl 4 strokes, and also the race track ready Laverda SFC750 and all Yamaha's like RD350 /400 and even the V-Max. Add the Suzuki GT750 Water Buffalo 2 stroke, the 750 and 1000 1977 and 1979 4 cyl 4 stroke bikes as well. Add in the BMW 1000. The only Norton she faced off against was the 850 Commando and my Bonneville dispatched her as well. I brought out my Bonneville in 1992 she was 17 years old and she won against the new Kawasaki Ninja 1100 Fuel Injected and Honda V4 Interceptor 1000 cc's. Yes they had more acceleration and a higher top speed. But light weight and much better handling won out, as I and my Triumph did truthfully win against them. It was publicly witnessed! I still have my Bonneville and she sits around 20 feet from me as I type.

[@PeterDad60]

Top speed of my Bonneville on the flats was 108 mph, down hill 110mph, down hill with a tail wind 112 mph. I removed the mufflers and ran open pipes and that slowed the top speed to around 105 mph on the flats she but had greater acceleration and also I never had to look at the tachometer because the open pipes were so loud that even in a race I could tell by ear when it was time to upshift. The bike was 395 lbs. stock and got down to around 365 lbs. w/o the heavy mufflers. I removed the seat cushion to be lower in the bike and installed drag bars so I could duck down under the wind. No other mod's, stock KH-70 Dunlap Tires, stock motor, stock ignition, stock carb's, stock gear ratio's. She would never allow any other machine to head her, she always asked, nay demanded me to down shit a few gears and fully open her throttle. She never cut off another machine as she had manors even when racing to the point of death. I'm 67 now and do not ride her because I doubt that she has changed. I have nothing too prove anymore and I would not want some kid on a fast bike thinking he beat my beloved Bonneville. Hey she raced for more years than most other bikes survive. I really do ride at 20/25/30 and 35 mph when no one is around. I enjoy the sunshine, fresh air and the beauty of Tennessee and I hope to do so for another 67 years. Retirement from street racing has it's benefits! Everyone have a great riding season!

The RC166 sounds like a vintage F1 car! The RC116 has an unusual look to it, like they took your grandma's 3 speed and put the motor and body kit on it. (And even left the front fender!) I wonder why they left the rim brakes on it though. I would think they would get hot since the wheel is travelling faster through the caliper at the edge of the wheel than a rotor would be at the hub, but maybe it was more effective and the brakes were applied for a shorter period of time so heat wasn't a problem? Maybe a six of one/half dozen of the other situation?

I raced motocross in Japan in 1964 and 1965. My Honda 250 CB ,which was a road bike when I bought it, but was set up with larger wheels and the exhaust was routed up under the seat. It was a 4 cylinder, four stroke and had a small sprocket off the trans (4 spd) but a big sprocket on the rear wheel. The tracks were short and my top speed was around 65 mph. I would shift from third to 4th at 10,000 rpm. All I ever did to the bike was change chains, adjust the valves, change plugs. I had to replace the foot pegs with rebar, because coming off a jump, I bent the stock ones. I didn't do too bad. I was ranked the 11th best non Japanese rider. I would have ranked higher but I had to ship out (discharged) I did get a tour through the Honda factory because I did so well with their bike. I saw a 50cc 4 cyl Gran Pre bike that would do 20,000 rpm. the clyinders were just big enough for a dime to fit. Stupid me I sold the bike to a guy who put it back on the street. I should have sent it home and opened up a Honda shop. There weren't any dealers yet in the States.

I need some help. In the beginning he said that low piston speed is part of a recipe for a high revving engine. How can low piston speed mean higher revolutions per minute? The higher the rpm, the faster the crank/Conrod/piston is moving, right?

[@brianrushford4057]

You think the Honda guys realise what a brilliant job they have

[@normanabdullah6090]

Used to owned the ZX250R with mods and custom pipes...Powerband is around 8000-16000rpm and you will hear an F1 gear change

[@russelldawkins3408]

6:16 this sort of treatment is abusive to the engine and makes me cringe. To take any engine to redline with no load is hard on it; that's why some racing engines for cars have different redlines for each gear-lower redlines in lower gears and higher in higher gears when the cylinder pressure is higher, keeping the piston straighter in the bore, preventing 'piston slap' where the skirt scrapes the bore due to centrifugal force near TDC and BDC. Notice at 6:30 the rider then proceeds to take the bike to redline in 1st and almost in 2nd. If you want to take care of a high revving engine short shift in the lower gears. Almost as bad is revving high then cutting the ignition immediately when shutting down, as some of these show-offs are doing. This covers the cylinder walls with raw gas, dissolving the small amount of oil on the bore and creating wear with the next start with dry cylinder bores... The motor should be allowed to idle for a couple of seconds before shutting down.

[@anthonydomanico8274]

Russell Dawkins, sounds reasonable. I was thinking to myself that’s the way they sit there and rev these engines is annoying. I’d much rather hear the engine wide open ripping down the track under load. That’s when engines sing! Those high revving four strokes sound like big bore two strokes since they are having so many power strokes per second!

[@marvstrickler9573]

I recall in the 1970's, Suzuki made a six-cylinder 50 cc engine, = 27,000 rpm, 2 stroke prototype however.

love the videos. but i think your old format where you just play the audio from the videos and have text written on the screen is better since the sounds of the engines is audible.

The new Kawasaki zx4rr is a high revving inline 4, they’re back!!!
