This machine is not designed for British roads.The main problems were excessive smoke,hard to start,and the tyres supplied were lethal on smooth road surfaces.Also the rear sprocket was obviously made for hilly country roads,and the top speed was hindered by this. Overall, with modifications these problems once overcome releases the true potential of a machine easy to service and maintain.Carry a spare split link and set of points together with the original toolkit in the side panel and this bike is capable of 100,OOO MILES.
