A 20000rpm red line. Amazing for the period. I think this 125-5cylinder, was basically formed from the Honda 50cc twin, in order to demonstrate the art of miniaturisation. I think this machine had an eight speed gearbox. What I like about Honda, is they are never affraid to go beyond existing bounderies in order to make new levels. Many love Ducati for their Desmotronic engine and say Honda isn't anywhere close, but they have done things Ducati has never even tried.

Honda sold a street bike - the CB160 - that had a 10,500 rpm redline. In 1965. And unless I'm wrong, the video shows th bike revving only to about 12,000.

@@caribman10 I am in the process of restoring one of those old CB160's. Lovely little bikes. I've ridden a JDM market CBR250RR from the early 90's that rev to 19,000rpm. What amazes me the most is how reliable they are. My co-worker bought one after lusting after my VFR400R for a couple years. It's got over 40,000km on it and runs like a peach. Nothing has been done to the internals maintenance wise, not even valve clearances. I was lucky to take it out a couple of times. A small displacement 4 cylinder engine that revs that high is certainly a different approach to today's learner bikes, which is extremely unfortunate. It's something else to experience riding one. I can only imagine how cool the 250 6 GP bikes would be to ride.

Forgot to mention this in my previous post. I'm sure many people noticed that the Tachometer on this Bike starts at 5000rpm. When you consider the average automobile's redline even for V8's was around 5600rpm, it makes this motorcycle engine all the more incredible. Too be able to stay together in RR's turning as high as 20,000 rpm and barely going below 12 to 14 grand in many races is a testament to the amazing engineering and quality made parts for these machines. There reliability was astounding; you rarely ever heard of them blowing up which wouldn't surprise anyone turning that kind of RPM

Longer Stroke engines do not rev high rpm. Case in point BSA B34 Goldstar undersquare at 85mm Bore x 88mm Stroke. If you raced them consistenly past 7600rpm, then you rebuilt the bottomend multible times during the race season or they just broke a Rod wiping out the main cases. Same scenario with H-D's old Racing KR 750cc Flathead/SV engine, undersquare long stroke, they didn't want these engines reving past 7000rpm. Both engines had roller bearing lower ends. Current Alloy XR750 is being reved to almost 10 grand on Grand National Caliber engines and needs a bottomend rebuild almost every race. Engine originally designed in the early 70's with 10-1 compression and 8000rpm redline. Now running close to 10 grand with the aid of titanium valve and lighter valvetrain components and having close to 13-1 compression ratio, they have become gernades and too expensive for privateer riders to maintain. Even causing 2 Former GN Champions to jump to INDIAN'S new FTR750 for the 2017 race season. H-D team will field their new XG750R. Both these engines have strokes around 65mm with Indian having a 53 degree V angle. Their Redline is right at 10 Grand...

A mechanic simply picked up the front end of the bike and held it vertical until the excess fuel drained out of the carbs. That's how light and compact they were.

Pretty sure that's the RC149 5cyl 125cc RRer produced in 1966 after the RC148 was developed in 65. Since Honda was pulling out of GP Racing around this time, the little 125 didn't see that many races. Their Powerband was so narrow they needed an 8 speed gearbox to compensate. The piston diameter of these engines was about the size of a 50 cent piece. Another Engineering Marvel from Honda Racing in the 60's ...

@schlusselmensch Honda came up with the CVCC engine which eliminated the need for catalytic converters. Ducati's desmo allowed the valves to be power opened and power closed, thus not needing coil springs. However, Honda came up with a different idea on their CB400T, whereby the valves use torsion bars to close them, therefore reducing valve bounce at higher revs. Better than coils, but less expensive than desmo, but almost as effective.

Honda's CVCC engine was also remarkable, but never went into production for the motorcycle, but worked quite well for the car as it never needed a catalytic converter for the regulations of the day. Also their rotary engine which was adopted for the CB125, never made it because it failed on the emissions (I think the NOxs where to high).

@alna1287 I don't think the 5 cylinder 125 had oval pistons, but the NR500 of 1979 did. Regulations of the day did not allow V8s, but Honda wanted a high revving four-stroke. An engineer was sat at a set of traffic lights in his car and noticed eight lights in an oval. He then thought of the idea of eight valves and four oval pistons, thus allowing a high revving 500cc four-stroke V4. Each piston has two con-rods, enabling the rpm of a 500cc eight cylinder. The NR didn't defeat the two-strokes.

The 450 didn't sell in huge numbers if I not mistaken. Was the 450 the one that had the torque converter? The torsion bar system is a good idea and so is the desmo, but nearly all engines still use coil springs so the other two ideas must have their drawbacks. Honda had a proposed CX360 but never produced it
