The RFX Pro Series 520 aluminum sprocket is designed for off-road use: trials and motocross. CNC machined from 7075 aluminum, it features a CAD-optimized profile to reduce weight without sacrificing mechanical strength. The black anodization and the laser-engraved RFX logo give it a sleek look that is resistant to track wear.
Its mud evacuation grooves have been integrated into the finish to facilitate cleaning and limit buildup between the chain and sprocket. The tight machining tolerances contribute to smoother transmission operation, while the rigid design aims to minimize deformation under load.
Designed for demanding riders, this RFX sprocket is a technical and visual choice to enhance your drivetrain without adding weight to the machine.
