Moto-Master Fusion Series 520 Dual Ring Rear Sprocket Orange

The Moto-Master Racing Fusion Dual-Ring rear sprocket gives you the best of both worlds: a steel outer ring and a lightweight aluminum inner ring.

The rear sprocket´s outer ring is made of specially hardened and nickel-coated steel and the inner ring of 7075-T6 aircraft aluminum. The Fusion Series Dual Ring lasts up to 3 times longer than an aluminium sprocket and weighs up to 50% less than a standard steel sprocket.
