Renthal Twinring Rear Sprocket 50 Tooth Black Honda (1540-520-50GPBK)

The Renthal Twinring rear sprocket combines lightweight performance with long-lasting durability for Honda motorcycles. The inner ring is made from high-strength Ultralight™ 7075 T-6 aluminum, while the outer ring uses electroless nickel-coated steel for excellent wear resistance. This two-material construction delivers the reduced weight of an aluminum sprocket with the extended service life of a steel sprocket, helping the Renthal Twinring last up to three times longer than a standard all-aluminum sprocket while remaining lighter than an all-steel rear sprocket.
The outer ring is expanded during manufacturing and fitted over the aluminum inner ring using an interference fit. Combined with the engineered wave pattern, this process creates a permanent bond designed to remain secure throughout the life of the chainwheel. Flat socket-head screws provide additional strength during side impacts and help eliminate interference with the chain guide, supporting reliable performance in demanding riding conditions.
Self-cleaning mud grooves between each tooth help prevent dirt buildup, reduce chainwheel wear, and contribute to the sprocket’s low-weight design. The black finish provides a clean, race-ready appearance, while the precise 50-tooth configuration is engineered for compatibility with the specified Honda application. The Renthal Twinring rear sprocket, part number 1540-520-50GPBK, is a durable replacement or performance upgrade for riders seeking dependable drivetrain performance, reduced rotating weight, and extended sprocket life.
