Product details
These JT steel rear sprockets are billed as the new standard for motocross. Their self-cleaning design keeps the contact area clear of dirt and mud, and it cuts weight significantly too.
Heat-induction hardened C45 steel gives up to six times the life of a 7075 aluminium sprocket, and your chain lasts much longer as well.
