The Renthal 99+ Yamaha YZ series rear grooved sprocket is engineered with high-performance materials to optimize your motorcycle's power transfer and durability. Crafted from high-strength 7075-T6 aluminum, this sprocket is approximately 33% lighter than traditional steel sprockets, helping to reduce overall weight and improve handling without compromising strength. Its specialized tooth profile ensures smooth chain engagement, allowing the chain to roll easily on and off the sprocket, which extends wear life and reduces noise during operation. This design feature contributes to a more efficient drive system and enhances rider confidence on the trail or track. CNC-machined for precision, the sprocket features an ultra-light computer-aided design that reduces unsprung weight, leading to improved suspension responsiveness and overall bike performance.
