Renthal Twinring Rear Sprocket 48-Tooth Silver for Honda (1540-520-48GPSI)

The Renthal Twinring Rear Sprocket combines a lightweight 7075-T6 aluminum inner ring with an electroless nickel-coated steel outer ring for an effective balance of performance, durability, and reduced rotating weight. Designed for compatible Honda applications, this 48-tooth silver chainwheel uses premium materials and a precision-engineered construction to provide reliable power transfer in demanding riding conditions. The Renthal part number is 1540-520-48GPSI.
The outer ring is expanded during manufacturing and fitted over the inner ring to create a secure interference fit. This construction, combined with the wave-pattern design, forms a permanent bond intended to remain dependable throughout the service life of the chainwheel. Flat socket-head screws reinforce the sprocket during side impacts while helping prevent contact with the chain guide, supporting smooth and confident operation on the trail or track.
Self-cleaning mud grooves between each tooth help prevent dirt buildup, which can reduce chainwheel wear and maintain consistent chain engagement. The lightweight design uses only the necessary material to minimize weight without sacrificing strength. Compared with a standard all-aluminum sprocket, the Renthal Twinring is engineered to last up to three times longer, while remaining much lighter than a conventional all-steel rear sprocket. For riders seeking a durable, high-performance replacement rear sprocket, the Renthal Twinring 1540-520-48GPSI delivers dependable construction and optimized weight savings.
