Originally fitted with cast iron heads, a redesign in 1972 saw an all alloy motor with a revised bore/stroke. 82hp at 7,700rpm. Dry weight 134kg. Top speed 185kph. This a 1975 model and has been restored to the specification it finished its racing career. The frame, motor, wheels & tank are original.
