Features

RFX Pro Series Elite Aluminum Sprocket - 420

Manufacturer reference: FXRS 25-49 99GN

Designed for off-road use, this RFX Pro Series Elite sprocket is CNC machined from 7075 aluminum for an optimal balance between lightweight and mechanical strength. Its green anodized finish allows for quick identification of the color-coded RFX mounting according to the brand, while the laser-engraved logo confirms the authenticity of the part.

Material: CNC machined 7075 aluminum
Number of teeth: 49 (pitch 420)
Chain pitch: 420
Mud evacuation grooves to limit clogging
Lightweight CAD profile with tight tolerances
Optimized cut and stiffness to reduce deformation under load
Color: anodized green (model code)

The release grooves evacuate mud and help extend the lifespan of the chain and sprocket on your motocross outings. A standard replacement part, it is aimed at motocross and enduro riders who want a robust, precise, and lightweight sprocket for reliable performance.

Main compatibilities: KAWASAKI KX 85 II (2026), KAWASAKI KX 85 I (2026), KAWASAKI KX 85 STD WHEELS 17/14 (2021).
