Speed Calculator

This calculator will estimate a projection of how fast a motorcycle will travel based on the basic gearing setup. This calculator does not take into account any information such as horse power or determine torque so while a configuration may estimate a particular speed it does not necessarily mean that you will be able to achieve it.

The default options are setup for a 1982 Maico 490 GS and an explaination of how this works can be found here. Transmissions which do not have a seperate layshaft (and only a countershaft/driveshaft) can simply enter 1 for both the driveshaft sprocket and the layshaft sprocket entries in the supporting information. Bikes that do not have a 5th or 6th gear can just extend the highest gear settings.
