Supersprox Stealth Sprocket 2009-2014 Aprilia RSV4 Factory

Supersprox-stealth is about longer life, without compromising weight. Primariy goal, to last 3 times longer than an all aluminum sprocket and remain as light as possible. It's about performance and function first and last.

Supersprox-stealth is infinitely better than steel. You just can't achieve this level of strength on a steel sprocket with the same weight. Sure, there are light steel sprockets out there, but they can't handle the torque Pound (lb) for foot pounds (ft/lbs) Supersprox-stealth are the best.
