In low traction conditions a flywheel weight can assist the rider in making the most of the available engine power by giving more control / not excessively breaking traction or ‘spinning up’.

Flywheel weights will not add any torque or do anything other than moderate the speed that the engine ‘spins up’.

This is the same flywheel weight that we have developed in our racing program which gives the best balance between traction and not making the engine feel too lazy and slow in response.

We are choosing not to publish the actual weight as there has been some expense in the development which we’d like our customers to enjoy exclusively. We are happy to supply specific weights if needed.

If you don’t have a flywheel puller you can get one here. (not necessary to install but does make it easier and useful to have)
