105 kph

Max Power

(13.7 hp) 10.2bhp (7.6kW) @ 8500rpm


didnt expect 65 mph

However seems strange its as fast going up a 1 mile reasonably steep hill as it is on the flat

I once had 75 ( indicated ) out of a 1976 CG 125 on level ground with my weight at around 17 stone . I think the very early ones had a bigger carb . If memory serves, the engine was a hybrid that I knocked up from a Brazilian bottom end and a Japanese top end with a fresh rebore . It crackled and popped a bit at slower speeds but was surprisingly quick when I opened it up . So to return to the OP , I think 40 mph is a bit weak by any standards .
