Supersprox/EK Chain And Sprocket Kits

Supersprox/EK Chain and sprocket kits are a great way to grab everything you need in one kit. 
Supersprox has been supplying the highest quality sprockets since 1959 and has grown to be one of the largest sprocket manufacturers in the world. Founder Roger Maughfling, who was extremely passionate about motorcycles, began producing sprockets as supply was lacking for the makes and models he needed. Over the years Supersprox has been set as the industry standard.

Supersprox Stealth was developed for riding in extreme conditions, where aluminium sprockets can't handle the torque delivered through the chain drive system. Supersprox engineers conceived and developed the combination of the two materials in the millennium year. Supersprox have counted 12 world titles since that time and 2005/06/07/09/10/11/12/13 Dakar wins.
