Anyone who changes the pinion, sprocket or a complete chain kit normally uses the standard number of teeth, so the secondary transmission remains the same. A change in the number of teeth results in a longer or shorter gear ratio between the motor and the rear wheel. If, for example, instead of a 16-tooth pinion at the transmission output, a 15-tooth counterpart is used, the engine speed is higher at the same speed – useful, for example, for enduro bikes that are mainly used in terrain.

A change to a 17 tooth pinion, on the other hand, would reduce the speed at the same speed – often used in performance-enhanced sports machines to increase the top speed or on tourers to get a low speed level. The opposite is true for the rear sprocket. The more teeth increase the engine speed, the fewer reduce it. It should be noted that if larger or smaller gaps or chain rings are used, the chain length often has to be changed, the adjustment range of the chain tensioner can bridge a difference of at most one or two teeth.

Important note: A change in the secondary ratio – the primary ratio takes place between the crankshaft and the gearbox input shaft – is not permitted and must be registered in any case, as the ratio is part of the operating license. Finally, it has an influence on the noise behavior and the top speed. If you want to register a different translation, you should definitely discuss this with TuV or Dekra beforehand.
