Renthal Rear Sprocket, 51-Tooth Aluminum, Black for Suzuki (123U-520-51GYBK)

Upgrade your Suzuki drivetrain with the RENThAL 123U-520-51GYBK rear sprocket, engineered for riders who demand efficient power transfer, reduced rotating mass, and dependable durability. This 51-tooth sprocket is CNC-machined rather than stamped, providing precise construction and consistent performance for demanding street, off-road, and competition applications. Its computer-aided ultra-light design helps reduce unsprung weight, allowing the drivetrain to respond more efficiently while maintaining the strength needed for reliable service.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with conventional steel sprockets, this material is approximately 33% lighter, helping reduce overall drivetrain weight without sacrificing essential strength. The lightweight aluminum construction supports sharper acceleration response and improved power transfer, making it a practical performance upgrade for compatible Suzuki motorcycles.
RENTHAL also incorporates a specialized tooth profile designed to help the chain roll smoothly onto and off the sprocket. This geometry promotes longer chain and sprocket wear, reduces operating noise, and helps deliver more consistent power transfer throughout the drivetrain. The black finish adds a clean, durable appearance that complements a wide range of motorcycle setups.
Choose the RENThAL 123U-520-51GYBK when you need a precision-machined, lightweight replacement or performance sprocket for a compatible Suzuki application. Verify your motorcycle's fitment, chain size, and gearing requirements before installation to ensure proper compatibility and drivetrain performance.
