Triumph Twin Gear Ratios

Featured Replies

Hello everybody, I am currently building a triumph twin (500) into a Whitlock frame, and would like some advice on sprockets. The engine is currently on standard sprockets, and I need to try to keep the rear(wheel) sprocket small, as it's quite crowded back there. That suggests I need to use the smallest driving sprockets available, which are 13t gearbox, and 16t engine. BUT I don't want to be having to tackle sections in top gear if I go too far, so- the question is, has anybody out there got any experience of the optimum sprocket combinations for a Triumph twin?

Thanks for that, 4stroke. I have a 14T gearbox, and 16T primary sprockets on the way from Dave at D&C. The rear he suggested was a 52, but I will have to see what will fit when I get the bike bolted together.
