The Suzuki RM Series, is the long running line of motocross competition motorcycles, emerged in 1975 as a purpose-built evolution of the brand’s earlier TM (Trail Motocross) models. Production began with the RM125 and RM250 and quickly expanded. Engines have historically been high-strung two-stroke singles, 125cc, 250cc, and later four-stroke variants like the RM-Z450, producing upwards of 50 hp in modern form. Drivetrains are chain-driven, with 5-speed manual gearboxes and no automatic options.
