The Renthal Twinring motocross rear sprocket is designed for dirt bike riders who want a durable, low-maintenance drivetrain component. Its dual-material construction combines a hardened steel outer chain ring with an Ultralight aluminum inner, providing a permanently bonded sprocket design.
During manufacturing, the steel outer ring is heated to 200 degrees C before being permanently fitted to the aluminum inner. This construction is intended to maintain the bond for the life of the sprocket while combining the properties of both materials in one rear sprocket.
This silver Renthal rear sprocket has 50 teeth and uses a 520 chain size. It fits select Kawasaki motorcycles, including 1987-1990 Kawasaki KX125, KX250, and KX500 models, as well as the fitment applications listed by the manufacturer. The manufacturer part number is 1120-520-50GPSI, and the vendor part number is 1120-520-50GPSI.
Fitment: 1987 Kawasaki KX125, 1987 Kawasaki KX250, 1987 Kawasaki KX500, 1988 Kawasaki KX125, 1988 Kawasaki KX250, 1988 Kawasaki KX500, 1989 Kawasaki KX125, 1989 Kawasaki KX250, 1989 Kawasaki KX500, and 1990 Kawasaki KX500.
