Ultra light (3.87kg – 8.53lbs) EN8 steel billet race flywheel for diaphragm clutch {NOT-Verto} with ring gear for non-pre-engaged starter.

Forged is more rigid at high speed. The latest refinement of the Ultra-light Mini flywheel is now made symmetrically to reduce harmonics vibrations caused by earlier version. Yet it still weighs under 4kg. This is considerably lighter than a safely lightened standard iron flywheel, and also provides a much hardier clutch surface.

Not recommended for road use. (See C-AEG421 FOR FAST ROAD)
