The Renthal Twinring rear sprocket is designed for dirt bike use and combines a hardened steel outer chain ring with an Ultralight aluminum inner. During manufacturing, the steel outer ring is heated to 200°C before being permanently fitted to the aluminum inner, creating a bonded dual-material sprocket design intended to remain together throughout the sprocket's service life.
This black Renthal rear sprocket has a 520 chain size and 51 teeth. It fits select Kawasaki KX125, KX250, and KX500 models from 1987 through 1990: 1987 KX125, KX250, and KX500; 1988 KX125, KX250, and KX500; 1989 KX125, KX250, and KX500; and 1990 KX500.
