Renthal Twinring Rear Sprocket 48-Tooth Black (1500-520-48GPBK)

Upgrade your motorcycle’s drivetrain with the Renthal Twinring rear sprocket, part number 1500-520-48GPBK. Designed for select Honda and Yamaha applications, this 48-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 black finish provides a clean, race-ready appearance while supporting the sprocket’s performance-focused construction.
The inner ring is manufactured from high-strength Ultralight 7075-T6 aluminum, the same premium material used in Renthal’s standard sprockets. The outer ring is made from electroless nickel-coated steel for enhanced wear resistance and durability. Renthal uses a precision interference-fit process, expanding the outer ring at 392°F before fitting it over the inner ring. Combined with the distinctive wave pattern, this construction creates a permanent bond designed to remain secure throughout the life of the chainwheel.
Additional performance details help the Twinring sprocket withstand demanding riding conditions. Flat socket-head screws reinforce the chainwheel during side impacts while reducing the chance of contact with the chain guide. Self-cleaning mud grooves between each tooth help prevent dirt buildup, reducing chain and sprocket wear while also minimizing unnecessary weight. Compared with a standard all-aluminum sprocket, the Renthal Twinring is engineered to last up to three times longer while remaining substantially lighter than an all-steel rear sprocket.
