The MB50 was the road-going sister of the MT50 trail bike, a 49 cc two-stroke sports moped styled like a miniature racer for 16-year-old riders. It had Comstar wheels, a hydraulic front disc and a balancer-shaft engine that was unusually sophisticated for its class. In the US and Canada it was sold as the MB5, imported only for 1982, while European sales ran until 1988.
