Renthal TwinRing Rear Sprocket 50 Tooth Black for Honda and Yamaha (1500-520-50GPBK)

The Renthal TwinRing Rear Sprocket combines a lightweight 7075-T6 aluminum inner ring with a highly durable nickel-coated steel outer ring for dependable performance in demanding off-road conditions. Part number 1500-520-50GPBK features a black finish and a 50-tooth design for compatible Honda and Yamaha applications. This hybrid construction delivers a balance of reduced rotational weight, long service life, and reliable chain engagement.
The steel outer ring is expanded during manufacturing and fitted over the aluminum inner ring to create a strong interference fit. Combined with Renthal’s wave-pattern design, this construction forms a permanent bond intended to remain secure throughout the service life of the chainwheel. Flat socket-head screws further reinforce the sprocket during side impacts while helping prevent contact with the chain guide.
Self-cleaning mud grooves between each tooth help minimize dirt buildup, reduce chain and sprocket wear, and maintain consistent performance in muddy or abrasive riding environments. The TwinRing design is engineered to last up to three times longer than a standard all-aluminum sprocket while remaining significantly lighter than a comparable all-steel rear sprocket. The result is a durable, high-performance replacement for riders seeking weight savings without sacrificing longevity.
