Here is a bike restored by Bert Spicer & Tony Cooper last winter.It’s a
1954 model 20, 500 cc
It was in a poor state & had been standing for many years. It was stripped, the engine rebuilt, the frame powder coated ,all the tin ware re-sprayed, new loom, electronic ignition,rebuilt wheels with new rims & spokes. I wouldn’t like to say how many hours were put in but the results speak for them self.
