1930 CS1 Norton

This is a 1930 CS1 Norton that was entered for the 1930 TT races; the rider is Mr Tim Hunt. Obviously, the Norton has a Carroll engine in a three stay frame. The high resolution picture was copied from the April 2010 issue of "The Classic Motorcycle" and shows a few remarkable details I had not noticed before.


Both tanks are polished and plated in chrome or nickel and so are the handlebars and clamps. It still has inverted levers; the throttle is operated via a modern twist grip  The brake plates are of a very light color, were they plated too? Spokes and rims were painted black while the nipples were plated. The rear wheel is 19" while the front rim is 21". The front forks are heavy duty TT Webbs; note the rubber stops fitted below the lower spindles. The anchor of the Andree steering damper is still fitted to the top of the petrol tank. The engine still has an oil return pipe from the cambox to the crankcase like the Moore engines. The petrol pipe is in rubber covered by a metal spring. The magneto is an ML 'square body'. The metal box in front of the cylinder contains oil to lubricate the primary chain. The gearbox probably is a Sturmey Archer 4 speed and has a positive stop mechanism fitted.
