History
The RM (standing for racing motorcycles) 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. Manufactured from 1978 to 1980, the machine had an air cooled, single cylinder two-stroke engine with a displacement of 402cc and a 6.7:1 compression ratio.
Engine
A 80.0mm bore x 80.0mm stroke result in a displacement of just 402.0 cubic centimeters.
