Description
The Renthal Ultralight Rear Sprocket is a high-performance upgrade designed for the 1989-2006 Yamaha YFZ 350 Banshee and YFM 660 Raptor. Precision CNC machined from 7075-T6 aluminum alloy, this sprocket is 66% lighter than steel while maintaining exceptional strength and durability. Engineered for motocross, supercross, and enduro applications, it features an advanced tooth profile for maximum power transfer, improved concentricity, and precise fitment. The hardwearing surface treatment extends chainwheel life, while self-cleaning mud grooves help prevent dirt buildup.
