Always wanting to loose more bike weight over the winter...
...next was the clutch. Particularly relevant since it turns (gyro effect) and it is directly connected to the engine (quicker revving).
I read promises of dramatic weight loss with lightweight clutch baskets, plates, hubs etc.
Well... not quite. With the Sport Classic line, Ducati has gone pretty light already. The OEM clutch basket is in aluminum and aftermarket baskets may save 1 or 2 ounces at most. Lightweight plates promising a 1/2 lbs weight saving, turned out to be 1/4 lbs (100 g) lighter only.
But. Aftermarket clutch HUBS appear to be a full 1.25 lbs lighter than stock (580 g) !!
I should have wondered why >1 lbs weight difference between two like aluminum parts. I didn't.
Turns out the difference is a cush drive clutch hub system OEM (very much like the rear wheel cush drive), versus a simple direct transmission aftermarket (also called "race clutch hub").
Not surprisingly, the cush drive is said to absorb possible sudden impacts to the transmission.
I mounted the race clutch; I never intended to go "the long way around" with my PS, I want it to be a pretty extreme, and classy 1100 SS that Ducati never built
I wonder if anybody has an experience with these "race clutch hubs" in a 2-valve or any other ducati, or if there are any strong opinions out there
