| My clutch cover on the track bike is very similar to that one from Casoli but I have less vents.
It looks very tough and I would assume that it is able to take impact very well as well as scrubbing on the tarmac.... although I have never guinea-pigged that myself. Looks tougher to me than the standard cover as well.
It doesn't show the slipper clutch much, but what should you care. It is there for efficiency during downshifts, not posing value!! |
