Renthal TwinRing Rear Sprocket 50-Tooth Green for Kawasaki and Suzuki (1120-520-50GPGN)

The Renthal TwinRing rear sprocket, part number 1120-520-50GPGN, combines lightweight performance with long-lasting durability for Kawasaki and Suzuki motorcycles. Its inner ring is made from high-strength Ultralight 7075-T6 aluminum, while the outer ring uses electroless nickel-coated steel to resist wear and maintain reliable chain engagement. The green finish adds a distinctive appearance while preserving the sprocket’s race-ready design.
The outer steel ring is expanded during manufacturing and fitted over the aluminum inner ring to create a secure interference fit. Combined with the engineered wave pattern, this construction forms a permanent bond designed to remain reliable throughout the life of the chainwheel. Flat socket-head screws provide added strength during side impacts and help prevent contact with the chain guide, supporting consistent performance in demanding riding conditions.
Self-cleaning mud grooves between the teeth help prevent dirt buildup, reduce chain and sprocket wear, and minimize unnecessary weight. The TwinRing design is engineered to last up to three times longer than a standard all-aluminum sprocket while remaining significantly lighter than an all-steel rear sprocket. This 50-tooth Renthal sprocket is a strong choice for riders seeking an efficient balance of reduced weight, durability, and dependable drivetrain performance.
