Description
If you’re running a 520 chain setup on your Kawasaki dirt bike, sprocket weight matters more than most riders realize—a lighter rear sprocket directly reduces unsprung mass, improves throttle response, and decreases rotational inertia for snappier acceleration. The Renthal 51-tooth sprocket cuts weight by 66% compared to steel while maintaining the durability needed for aggressive riding, and its self-cleaning tooth grooves eliminate mud and debris buildup that can rob you of consistent power transfer.
Built from CNC-machined 7075 T6 aluminum and protected with a hard-anodized finish, this sprocket delivers the precision engineering you expect from Renthal—a brand trusted by professional racers and serious enthusiasts alike.
