ProX Alloy Rear Sprocket YZ/WR250/400/426/450F '98-23 -48T

ProX offers a complete range of front and rear sprockets.
The ProX alloy rear sprockets are all manufactured from high-grade 7075-T6 material. The total sprocket is precision cut on fully automated CNC machines using strict tolerances, guaranteeing a perfect fit. The sprockets come with self-cleaning mug grooves. Unlike many other rear sprockets, the specially designed mud grooves are positioned outside the pressure area of chains and sprockets to increase durability significantly.
