A smaller version of the 500 Mach III, it was manufactured from the late 1960s. Although it featured a smaller engine, it had characteristics very similar to the 500. The frame was a duplex cradle design with telescopic suspension and drum braking, while the engine featured a shaft rotating on six main bearings, designed to support the over-abundant engine torque. The lines differed slightly from the Mach III, it had a long and slightly raised saddle, a more rounded tank and a slightly larger front headlight.
