Renthal Twinring Rear Sprocket 49-Tooth Silver for Honda (1540-520-49GPSI)

Upgrade your Honda motorcycle’s drivetrain with the Renthal Twinring rear sprocket, part number 1540-520-49GPSI. This 49-tooth sprocket combines a high-strength Ultralight 7075-T6 aluminum inner ring with an electroless nickel-coated steel outer ring for an effective balance of low weight, strength, and long-term durability. The silver finish provides a clean, technical appearance while the proven two-piece construction is engineered for demanding riding conditions.
The steel outer ring is expanded during manufacturing and fitted over the aluminum inner ring to create a secure interference fit. Combined with the wave-pattern design, this construction forms a permanent bond intended to remain reliable throughout the service life of the chainwheel. Flat socket-head screws reinforce the sprocket during side impacts and help prevent interference with the chain guide, supporting consistent performance on the trail or track.
Self-cleaning mud grooves between the teeth help release dirt and debris, reducing buildup that can accelerate chain and sprocket wear. The lightweight design uses only the material required for strength, making the Twinring substantially lighter than a comparable all-steel rear sprocket. Renthal states that the Twinring can outlast a standard all-aluminum sprocket by up to three times, offering a durable replacement for riders who demand dependable drivetrain performance.
