Sigma Performance

In the past we have serviced and built many Ducati's. As an information resource to the Ducati community we have maintained our web pages with their thought-provoking information on many aspects of Ducati ownership, ranging from racing and trackdays to normal road use.

Sigma Performance now specialises in the slipper clutch market providing many different designs and technical options for over 50 different bikes. From simple Ducati road and track day fittings to clutches that regularly get podiums in World Supersport. Neil Spalding of Sigma also attends most MotoGP races as one of the top technical journalists in motorcycling.
