Product details :

Features

The RFX Pro Series Elite sprocket made of 7075 aluminum is designed for motocross riders seeking durability and lightweight performance on the trails. CNC machined and anodized in orange, it features an optimized CAD profile and mud evacuation grooves to minimize chain clogging. Ideal for small displacement off-road bikes, it combines a racing look with mechanical precision.

Reference: FXRS 51-46 99OR
Material: CNC machined 7075 aluminum
Color: Anodized orange
Number of teeth: 46 teeth
Chain pitch: 428
Brand: RFX - laser-etched logo
Benefits: mud evacuation grooves, CAD profile to reduce weight, rigid design for better torsional resistance

Designed to be mounted as a standard replacement, this sprocket is particularly suitable for recent 85cc models (KTM 85 SX, Husqvarna TC 85, GAS GAS MC 85, among others). It offers a neat finish and tight machining tolerance for precise chain engagement, useful in muddy conditions and on aggressive terrains.
