Renthal Twinring Rear Sprocket 50-Tooth Black Suzuki (1230-520-50GPBK)

Upgrade your Suzuki drivetrain with the Renthal Twinring rear sprocket, part number 1230-520-50GPBK. This black 50-tooth chainwheel combines a lightweight Ultralight 7075-T6 aluminum inner ring with an electroless nickel-coated steel outer ring for an effective balance of reduced weight and long-term durability. The steel outer ring uses only the material required for strength, helping make the Twinring significantly lighter than an all-steel rear sprocket while providing substantially greater service life than a conventional all-aluminum design.
The Renthal Twinring construction is engineered for lasting performance under demanding riding conditions. The outer ring is expanded during manufacturing and fitted over the inner ring using an interference fit. Combined with the ring’s wave pattern, this process creates a permanent bond intended to remain secure throughout the chainwheel’s service life. Flat socket-head screws add reinforcement during side impacts and help prevent contact with the chain guide, supporting reliable operation on technical terrain.
Self-cleaning mud grooves between each tooth help shed dirt and debris before buildup can accelerate chainwheel wear. The result is smoother chain engagement and improved resistance to abrasive conditions. Designed for Suzuki applications, this Renthal Twinring sprocket delivers a durable, lightweight replacement for riders seeking dependable rear-drive performance without the added weight of a solid steel sprocket.
