Question : the reason he keeps reving the bike is because the engine is insanely compressed and because to be able to run that fast 170+ in lower ccs you'll need to sacrifice any thing below 4000rpm ... All guess I'm i correct ?😃
+Nazimelon Im not sure if you can actually get a replica of this engine, it is a race engine so its not designed to go very long and parts would probably be a problem
Mikkel Plougmann race engines can be reworked and scaled down to last longer and be more useable. of course they loose parts of their power and all but it still would have some of its charme.
@@nazimelon6653 there's some custom shop here in my country named psycho engine that able to make a radial 5 engine, L 2 (V 2) engine, W 3 engine, boxer 2 using a single cylinder engine, other workshop is OM2S and many more lesser known workshop
@@nigelmoore6519these engines had so little inertia they could not run without throttle input, I also believe they didn’t use idle jets in the carburetors.
@@BL4CKD3AD Well, it's predecessor, the 2RC146, didn't have those problems, and the other bike s at that kind of engine speeds didn't have those problems either. Nobody seems to know what caused it.
@@cidertom5140 Then why not the previous type, the 2RC146? And the other Hondas, the 50, 250, and 350 cc? And no other racing bikes seem to have problems with altitudes of the Isle of Man - after all, we're not talking of really high mountains!
@@joepkortekaas8813 Luigi taveri had problems with the rc 149 5/125 tuning and had to keep her above 17,000 to get it to run properly or it would cut out.
thank you for posting these videos, this is the only source I know of videos of vintage honda GP-Bikes
Just amazing!! The sound of fun!! Want one.
Could you imagine how terrifying it would sound with a 4 into 1 exhaust
I was wondering the same! It would absolutely HOWL
That noise is epic

ini prototipe balap om, apalagi ini motor jadul bgt, taun 70'an
The sound is amazing .how fast is he going ?
Why rev it so high
On the stand I mean

@@staticcorvette5998 thanks
125 by 4 it's not realy a 125 i think then
The engine's cylinders have a 35mm bore and 32mm stroke, giving 30.7cc per cylinder. Overall displacement of the RC146 4 cylinder engine is 123.15cc.
Alas, this bike was rather a failure, always having carburation and ignition problems, hardly ever running well.
Joep Kortekaas it runs on 18,000 RPM on a regular basis, that wouldn’t surprise me
