RC149(1966)です。
125cc 5気筒エンジンを搭載したGPマシンです。
1気筒あたりの排気量は25ccで，50cc 2気筒マシンRC116と同じです。
2ストに勝つ！という信念が成しえた奇跡のマシン。
その咆哮をお楽しみください。

250の166に比べて、扱い難いんでしょうね。50の116とかも誰でも乗れるレーサーって感じじゃ無いですね。１気筒25cc位ですから精密機械ですょね。これを60年代に作ったホンダは凄いですね。今のレーサーよりも良い音してますね。
やっぱり125か この車格で五発って夢の夢のマシンですね
気づいたのですが、エンジンをかけてからふかし続けるのには何の意味があるのですか？
ドライダー宮城カッコいい❗
もうに度と、高回転高出力のみを追求したレーサーをホンダが造ることはない。だから、もう二度とつくられない人類の宝、‼
こういう動画で聞こえてくる、近くの人の声ってのがマジでエモい
gives me goosebumps...can't imagine what red line sounds like...
I heard a great story about these things from a guy who went on to become a mechanic with Suzuki GB in later years. The engine was so miniaturised and access so difficult that changing jets required dropping the engine out of the frame but even then changing jets was so time consuming (and of course at race meetings time is a precious commodity) that Honda provided five engines for each bike and each one differently jetted so the tuning process involved selecting your "best guess" engine, fitting that to the bike and firing it up; the one that was able to free rev to 20,000 rpm was the one you ran with!
4 strokes 5 cylindres 20k rpm vs 2 strokes 2 cylindres 11k Rpm! What a race !!
Heard Jim Redman talking about riding these little beasts. Apparently below 10,000 rpm the engine would stop, he was sling off the bike and through a hedge on the island when he misjudged a gear change and let the revs drop!
25 cc per cylinder, that's crazy business!
An amazing piece of engineering
FAVOLOLOSA !!!! 125 cc, 5 cilindri 4 valvole per cilindro, 2 alberi a camne in testa, 4 tempi, girava a 24.000 giri !!!!!!!!!!!!!!!!!!!!!!! GIOIELLO !!!!
Assembling that engine required a watchmaker rather than an a mechanic.
What an incredible piece of engineering, what a shame that bikes like this aren't around any more. These were exciting days but those riders must have been superhuman to have kept them on the boil and not just made them competitive but won world championships with them. I'm assuming that this was a derivative of the Honda 50cc RC116 works twin?
Honda, I personally feel have actually lived the dream. They have dreamt about something and made it reality.
It sounds like 2 strokes cause it's so well done!!!

Sounds like a v10 f1. Sounds better than current f1 engines. And its a Honda!
Antigamente as máquinas eras muito mais legais do que as de agora...
