I think I have a more recent column compared to TR4/TR5, Mike. My horn is also on one of the stalks. The Taimar is a 1978 one. I think it is the same as the latest Tiumph Spitfire's. Can someone confirm?
Last time i bought a Moto Lita i drove to their premises that were in the middle of the Thruxton Circuit. That way you can look at different models in stock. I think you will need a flat Wheel unless you have long legs Alan
