[QUOTE="hadronuk, post: 114114, member: 1866"] When I bought my Rapide, it was fitted with a V2 clutch with the bronze coloured sintered metal friction plates, running dry. These offer the big advantage of a appreciably higher coefficient of friction than fibre plates running wet. So only light springs are needed. In turn, the lower lift force causes less deflection in the lift mechanism, so more lift. The plates also don't appear to wear out, in spite of doing some drag racing at Shakespeare County Raceway. The big downside is grab, which all-metal clutches are notorious for. Ducati MHR owners whose bikes are fitted with apparently identical plates cure grab with an extremely small amount of grease. Tried it, it works, but stronger springs needed and after about 600 miles the plates get sticky. My grab cure is to dip the friction plates in a 5% solution of dry lubricant and allow to dry, then refit. Minimal reduction in coefficient of friction, grab cured, minimal clutch drag. Clutch action is light and very similar to the standard clutch. Not quite sure how long this grab cure this is good for, as I foolishly removed my housing breather and a trace of oil vapour eventually made the plates slightly sticky after 2000+ miles. I expect to do better with the breather now reinstated. I should add that on my bike the housing cannot breathe via the dynamo mounting as that area was bodged and my repair is oil tight, so I bought a VOCSP reject ET63 and fitted a banjo for a breather pipe. Ducati sintered plates are still available so could be retro fitted to V2 clutches instead of the fibre faced plates. [/QUOTE]
