Product details :

Features

RFX Pro Series Elite Sprocket - aluminum 415, 42 teeth (Manufacturer part number: FXRS 55-42 99OR)

Designed for motocross, this RFX Pro Series Elite sprocket combines lightweight construction with precision. CNC machined from 7075 aluminum and CAD profiled, it offers a balance between rigidity and weight reduction for a more responsive rear end. The orange anodization and laser-engraved RFX logo provide a sleek look, color-coded to match your machine's brand.

Material: CNC machined 7075 aluminum
Number of teeth: 42 (chain pitch: 415)
Mud evacuation grooves to limit buildup and help extend the lifespan of the chain and sprocket
Optimized CAD profile to reduce inertia while maintaining necessary rigidity against twisting
Tight tolerances for smoother engagement
Orange anodized finish, RFX color code according to model

Compatible with listed small displacement motocross models (e.g., KTM 50 SX MINI, KTM 50 SX, KTM 50 SX PRO JUNIOR LC). Ideal for those looking for a racing-style sprocket that is easy to mount on the appropriate sprocket and ready to handle muddy track sessions.
