Ok, gotta brag here. You say Isle of Man and I say this bike of mine actually raced in the 1930 world cup at the IOM in fact, in 1930 Rudge finished 1st, 2nd, and 3rd and my bike finished 6th. I inherited it from my Dad who bought it in Vancouver, BC Canada from the guy who raced it at the IOM in 1930. I rode it a few months ago and it fired up first kick. Actually, it doesn't have a kick starter, you push and dump the compression release. In 1930, factory guarantee of 100 MPH. Check out the Shaun 84 Targa Thread on the t-Shirts he made based on the bike.
