Description

The Vortex Rear Sprocket for Yamaha R1S motorcycles is a high-performance upgrade. This 525 pitch conversion sprocket is made from premium 7075 T6 aluminum, offering riders a lighter and stronger alternative to the stock steel version. Available in 34 to 66 tooth sizes and finished in various colors, it enhances both performance and style while reducing rotating mass for faster acceleration.
