Product description
SC Lightweight Steel Rear Sprockets
The new standard in steel rear motocross sprockets. A unique self-cleaning design keeps the contact area clean from dirt and mud while significantly reducing weight. Made from heat-induction hardened C45 steel which lasts up to six times longer than a 7075 aluminium sprocket and greatly extends chain life.
