Renthal Rear Sprocket, 49-Tooth Aluminum, Silver (192U-420-49GPSI)

Upgrade your motorcycle’s final-drive performance with the Renthal 192U-420-49GPSI rear sprocket. Designed for Gas Gas, Husqvarna, and KTM applications, this silver aluminum sprocket combines lightweight construction with the strength needed for demanding off-road riding. Its precision CNC-machined design is not stamped, helping deliver consistent fit, durability, and reliable power transfer.
The Renthal rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum. Compared with a conventional steel sprocket, the aluminum construction is 33% lighter, reducing unsprung weight and helping your motorcycle respond more quickly during acceleration, cornering, and suspension movement. The reduced rotational mass also supports efficient power transfer without compromising the strength required for hard riding conditions.
A specially engineered tooth profile allows the chain to roll smoothly on and off the sprocket. This design helps reduce chain noise, promote even wear, and extend service life for both the sprocket and chain. The 49-tooth gearing provides a practical replacement or gearing option for riders seeking dependable drivetrain performance and precise engagement.
Built for riders who demand durable, race-ready components, the Renthal 192U-420-49GPSI rear sprocket offers a strong balance of low weight, smooth operation, and long-lasting performance. Verify motorcycle fitment, chain size, and gearing requirements before installation.
