Product details :

Features

Manufacturer Ref: FXRS 15-52 99RD — RFX Pro Series Elite aluminum sprocket - 420. Designed for off-road, this RFX sprocket combines lightweight and strength for motocross riders who want reliability and style on their bike.

Material: CNC machined 7075 aluminum, red anodized finish.
Number of teeth: 52 teeth — optimized profile for 420 pitch chain.
Design: CAD machined profile with tight tolerances for precise fit.
Drainage: mud relief grooves designed to limit accumulation and maintain chain and sprocket functionality.
Finish: laser-engraved RFX logo and specific color coding for a clear visual identity.

The rigid construction of this sprocket aims to reduce deformation under load, while maintaining a low weight due to machining. Ideal for rides and motocross sessions where mud and changes in RPM put significant stress on the drivetrain. Standard mounting, compatible with 420 pitch setups.

Common compatibilities: HONDA CRF 150 R (2026), HONDA CRF 150 R BIG WHEELS 16/19 (2022), HONDA CRF 150 R STD WHEELS 14/17 (2020).
