Product details :

Features

Manufacturer Ref: FXRS 10-49 99RD — RFX Pro Series Elite aluminum sprocket 520, 49 teeth (red). Designed for motocross/enduro practices, this rear sprocket is aimed at demanding riders who seek lightweight and reliability in muddy terrain.

Material: CNC machined 7075 aluminum for a good balance of stiffness/weight.
Teeth: 49 teeth, CAD-optimized profile to reduce weight without compromising strength.
Chain pitch: 520 — compatible with standard 520 transmissions.
Finish: red anodization and laser-etched RFX logo.
Terrain design: mud evacuation grooves to limit accumulation and preserve the lifespan of the chain and sprocket.
Machining quality: tight tolerances and rigid design for improved handling and torsional resistance.
Type: standard — available in several colors/brand coding for a proper fit on your machine.

Ideal for CRF riders and other motocross machines, this RFX Pro Series Elite sprocket is designed as a replacement for the listed models (see compatibility) and easily integrates into a 520 drivetrain.
