Difference between revisions of "Honda RC149"

To counter this challenge, Honda engineer Irimajiri (designer of the marque's 50cc twins and its six-cylinder 250) created a five-cylinder four-stroke made entirely from magnesium, for 1966. This amazing feat of engineering had pistons just 35 mm in diameter and cranked out 23,000 rpm yet stalled below 17,000 rpm, forcing the rider to work the nine-speed transmission relentlessly to keep the engine running! The Honda 125 proved unbeatable in the hands of the talented Swiss cyclist Luigi Taveri.
