Renthal Twinring Rear Sprocket 49-Tooth Black for Honda and Yamaha (1500-520-49GPBK)

Upgrade your motorcycle’s drivetrain with the Renthal Twinring rear sprocket, part 1500-520-49GPBK. Designed for select Honda and Yamaha applications, this black 49-tooth sprocket combines a lightweight aluminum inner ring with a highly durable steel outer ring to deliver long service life, dependable chain engagement, and reduced rotating weight. The Ultralight 7075 T-6 aluminum inner ring uses the same high-strength material found in Renthal’s standard sprockets, while the electro-less nickel-coated steel outer ring provides exceptional wear resistance for demanding riding conditions.
The Twinring construction is engineered for lasting performance. During manufacturing, the outer ring is expanded with heat and fitted over the inner ring to create a secure interference fit. Combined with the distinctive wave pattern, this design forms a permanent bond intended to remain secure throughout the chainwheel’s service life. Flat socket head screws reinforce the sprocket during side impacts while helping prevent contact with the chain guide, supporting reliable operation on rough terrain.
Self-cleaning mud grooves between each tooth help prevent dirt buildup, reduce chain and sprocket wear, and contribute to the sprocket’s low-weight design. Compared with a standard all-aluminum sprocket, the Renthal Twinring is engineered to last up to three times longer, while remaining significantly lighter than an all-steel rear sprocket. Choose the Renthal Twinring 49-tooth rear sprocket for a balanced combination of durability, weight savings, and race-proven drivetrain performance.
