The RFX Pro Series Elite sprocket made of 7075 aluminum (manufacturer reference FXRS 15-50 99BK) is designed for motocross riders looking for a lightweight and refined part for their drivetrain. CNC machined, it offers precise finishing and a CAD-designed profile aimed at reducing weight without sacrificing tooth geometry. Its anodized black color gives it a race-ready look that is resistant to the rigors of the terrain.
- Material: CNC machined 7075 aluminum
- Number of teeth: 50 teeth (sprocket)
- Chain pitch: 420
- Mud evacuation grooves to limit dirt accumulation between the chain and the sprocket
- Laser-engraved RFX logo and color-coded by brand for an aesthetic replacement
- Sturdy design with tight tolerances for precise positioning on the axle
- Available in multiple colors, anodized finish
Intended for off-road use, this sprocket is suitable as a standard replacement for compatible models, including the HONDA CRF 150 R (and Big Wheels / Std Wheels variants) listed as references. Chosen by riders who want reliability and style on their motocross bikes, it easily integrates into a 420 chain kit.
