SIGMA slipper clutches have proven themselves to be a reliable and tough addition to many a racing teams armoury. On their very first outing in a
Ducati back in 1998 they won a World Superbike support race at Donington and in 2004 at Brands Hatch won in their very first British Supersport race on Jay Vincent's Padgett's CBR 600. The Yamaha R1 2004
version also had a great year winning the Canadian Superbike championship with Pascal Picotte.
This section of the website is dedicated to slipper clutches, how they work, how to adjust them, where they came from and how to order one for your
own engine.
In Slipper Clutch we run through the history of the device; at least as far back as we know it and give a run through of the basics of slipper clutch operation.
The Slipper Clutch range gives details of our slipper clutch products; the bikes we can fit and the accessories that are available.
