Renthal 53-Tooth Rear Sprocket for Honda CR125R CR250R CR500R CRF150F CRF230F CRF250F CRF250R CRF250RX CRF250X CRF450R CRF450RL CRF450RWE CRF450RX CRF450X XR250R XR400R XR650R 154U-520-53GRSI

If you're running a Honda dirt bike or off-road machine, your rear sprocket directly impacts acceleration, top-end speed, and overall driveability. The Renthal 53-Tooth Rear Sprocket delivers a measurable weight savings and self-cleaning design that keeps your bike responsive in harsh terrain while resisting premature wear. Built from aerospace-grade 7075-T6 aluminum, this is a precision component engineered for riders who demand reliability without compromise.

The 53-tooth configuration works with 520-sized chains across Honda's extensive CR and CRF lineup, from the CR125R to the CRF450RX and XR models. CNC-machined construction ensures tolerances that steel sprockets simply can't match, while the integrated mud grooves actively shed debris instead of accumulating it—a critical advantage for motocross, trail riding, and enduro applications. At roughly 66% lighter than traditional steel alternatives, you'll notice improved handling and snappier throttle response, especially over a full moto.
