Not really a Termi article so its a seperate post.
My S is fitted with the Bucci Racing slipper clutch. Absolutely outstanding.
There are a few centre bearing slipper clutches out there, I have my doubts, but this one (not centre bearing) is the pooches pips. Its expensive, but it works - big time. Wack it down the box, any rev's, any speed - V-Twin - what V-twin!
Also check ou STM. An Italian manufacturer, they produce some sweet clutch covers.
As my jap 4 buddies tell me, it sounds bad with the open clutch cover!
Trouble is I always get there first!!
Needs regular cleaning tho'
