Renthal Ultralight rear sprockets will withstand the rigors of supercross, motocross, and enduro racing. Manufactured to extremely tight tolerances, they are 66 percent lighter than steel, and yet incredibly durable. Renthal uses computer-aided design, high-strength specially enhanced 7075 T-6 aluminum alloy, and CNC-machining to produce sprockets that are high-strength, hard-wearing, and offer the maximum reduction of unsprung weight at the rear wheel for maximum power transfer. They've also added self-cleaning mud grooves between every tooth on both sides to prevent dirt buildup. Shouldn't you choose the sprockets chosen by more factory race teams? Join a winning team and install Renthal Ultralight rear sprockets.
