I did some calculations for the inertia of a normal size clutch and it's about 2/3 of the Harley's massive crank, so too high I think.
From the parts diagram it looks like they reduced inertia by thinning and drilling the periphery of the flywheel, so it looks like the way to go.

So to be clear, clutch-specialists.co.uk get the M3W clutch parts from TTV?
