Serial bikes are often equiped with a very long gear transmission due to noise or exhaust regulations. In most cases these transmissions don´t fit best for racetracks. Often pinions with 1-2 teeth less and / or rear sprockets with 1-3 teeth more are used. In some cases a longer chain is needed. Only on racetracks with very high speed (e.g. Isle of Man, Hockenheim GP) and very narrow tracks (e.g. Fischereihafen in Bremerhaven) such an conversion will not fit best.
