        Description

        Sunstar is the largest OEM supplier of sprockets and brake rotors in the world. In fact, your motorcycle probably came from the factory with a Sunstar sprocket.

        Features:

        • Weighs up to 50% lighter than standard steel sprockets.
        • 100% heat treated AND even lighter than before with new weight reduction hole cut outs, but still has a hardness 5 times that of an aluminum sprocket and twice that of a standard steel sprocket.
        • Up to 4 times more durable with 1.2 times the lateral strength of any aluminum sprocket.
        • Great self cleaning capabilities due to the offset tooth design, same as the original Z sprocket which extends the life of the entire chain drive system.
        • The lightest STEEL sprocket available on the market.
        • *Note: Part is bike specific, may vary from image.

        Rated 5 out of 5 by from Fantastic, lightweight, durable, and self cleaning I purchased this 5 or 6 years ago, about 14,000km and the sprocket still looks new. I never clean my chain. And i oil it about once a week. I ride lots of gravel and mudd. Worth the extra money
