DescriptionRFX Pro Series Elite Aluminium - 420 Sprocket

Product details :

Features

RFX Pro Series Elite Aluminum Sprocket - 420: a part designed for motocross riders who demand lightweight, reliability, and mud performance. CNC machined from high-strength 7075 aluminum and anodized in blue, this sprocket combines aesthetics and durability. Its CAD-optimized design and tight tolerances ensure a precise fit with the 420 chain, while the rigid construction minimizes deformation under load.

Material: CNC machined 7075 aluminum
Number of teeth: 47 teeth (sprocket reference)
Chain pitch: 420
Finish: blue anodized, laser-engraved RFX logo
Design: CAD profile for weight reduction and mud evacuation grooves
Type: standard, specific color code for each model

The evacuation grooves facilitate mud clearance and limit premature wear of the chain and sprocket on muddy terrains. An ideal part for motocross use, it is available for many models while maintaining a standard format and robust finish.

Manufacturer reference: FXRS 56-47 99BU

Compatibility (examples): KTM 65 SX (2022, 2023) and KTM 60 SX (2000). Check the number of teeth and chain pitch before installation.
