Rear sprocket dual Yamaha YZ 65 2018-22 Z-46 420 steel/aluminum ZF blue

The Dual-Ring rear sprocket offers the best of both worlds: the outer track where the teeth are is made of steel and an inner ring of lightweight aluminum.

The outer track is made of specially hardened, nickel-coated steel, while the inner ring is made of 7075-T6 aircraft-grade aluminum. This system in offroad rear sprockets lasts up to three times longer than an aluminum rear sprocket and weighs up to 50% less than a standard steel rear sprocket.
