Renthal Rear Aluminum Sprocket, 47-Tooth, Silver (192U-420-47GPSI)

Upgrade your motorcycle’s final-drive performance with the Renthal 192U-420-47GPSI rear sprocket. CNC-machined rather than stamped, this sprocket features a computer-aided ultra-light design that helps reduce unsprung weight and improve power transfer. Its silver finish delivers a clean, professional appearance suited to GasGas, Husqvarna, and KTM applications.
The rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum, offering a significant weight advantage over steel while maintaining the strength required for demanding riding conditions. The reduced rotating and unsprung mass can contribute to more responsive acceleration, improved handling, and efficient power delivery without sacrificing durability.
Renthal’s specialized tooth profile is designed to help the chain roll smoothly onto and off the sprocket. This controlled chain engagement promotes longer sprocket and chain wear, reduces operating noise, and supports consistent drivetrain performance. The 47-tooth configuration provides a practical gearing option for riders seeking dependable performance across motocross, off-road, and other compatible applications.
Designed for select GasGas, Husqvarna, and KTM motorcycles, the Renthal 192U-420-47GPSI combines precision CNC machining, lightweight 7075-T6 aluminum construction, and a chain-friendly tooth profile in a reliable replacement or performance-upgrade component. Verify motorcycle fitment and drivetrain specifications before installation.
