The RM series of Moto-Cross machines were launched in 1975, replacing the old TM models. The range ran from 50cc right up to 400cc, and were very successful off the back of Suzuki’s World championship winning works machinery. By 1981 the models adopted liquid-cooling and the Full Floater swing-arm, a giant evolutionary leap in the handling stakes, giving Suzuki a real edge against the competition at that time. The extra performance of this model was achieved through more radical porting, which was hand finished. Re-designing the expansion chamber and a larger Mikuni carburettor complimented the additional port work.
