The legendary Supersprox Stealth sprocket motorcycle sprocket is the only hybrid sprocket available for street, MX, off-road and ATV's. Supersprox sprockets last longer, saving on running costs for your motorcycle, and they can offer a full range of sprockets for most modern motorcycles. Supersprox Stealth will last 3 times longer than an aluminum sprocket and is between 10 - 50% lighter than a steel sprocket (depending on model and tooth count). Supersprox guarantees that their sprockets will outlast, outperform and outshine the competition or your money back. Supersprox Stealth was developed for riding in extreme conditions, where aluminum 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.
