Features

RFX Pro Series Elite Aluminum Sprocket - 420 designed for motocross use. CNC machined from 7075 aluminum, this sprocket combines lightweight and rigidity to meet the demands of off-road riding. The mud evacuation grooves limit debris accumulation and help preserve the chain and contact surface over time.

Manufacturer reference: FXRS 25-54 99GN
Material: CNC machined 7075 aluminum
Color: anodized green (color code by model)
Type / Pitch: Standard — 420
Number of teeth: 54
CAD profile optimized for lightweight and tight tolerances
Stiff design for better torsional resistance

Designed for motocross machines, this Pro Series Elite sprocket is compatible with KAWASAKI KX 85 (listed models). Its anodization colors the part while providing an abrasion-resistant finish. Ideal for riders looking for a reliable and lightweight drive component, it installs as a standard replacement on 420 transmissions with 54 teeth.
