Features

Manufacturer Reference: FXRS 25-49 99BK

The RFX Pro Series Elite sprocket made from 7075 aluminum is designed for motocross riders seeking a balance between lightweight and durability. CNC machined and CAD designed, it features an optimized profile and tight tolerances for precise chain engagement on a 420 pitch. The black anodized finish and laser-etched RFX logo provide a polished look that withstands the rigors of off-road conditions.

Material: CNC machined 7075 aluminum
Number of Teeth: 49 teeth
Pitch: 420
Color: Anodized black
Mud evacuation grooves to limit chain/sprocket buildup
Optimized profile to reduce weight while enhancing stiffness

Designed for off-road use, this RFX sprocket facilitates maintenance and extends the lifespan of the drivetrain by removing typical motocross dirt. Its rigid construction helps better withstand the torsional forces encountered during cornering and jumping.
