Stealth Sprocket - Aprilia RSV1000 R / Factory / RSV4 R

Stealth sprockets are among the most technologically advanced sprockets in the world. The Stealth is a combination of a long lasting steel outer and a lightweight aluminium centre that utilises the best of both materials - The durability of steel and the weight saving of alloy.

Stealth will last three times longer than aluminium and twice as long as lower quality steel sprockets. The Stealth is not more expensive than alloy sprockets in real terms. Because the sprocket lasts three times as long, the cost versus life is much lower than that of aluminium. If you put on a high quality chain, don't ruin it with cheap sprockets!
