DescriptionRFX Pro Series Armalite Double Compound (Steel/Aluminium) - 420 Sprocket

Product details :

Features

RFX Pro Series Armalite Double Aluminum Sprocket - 420 (Ref. FXRS 15-56 ALRD)

Specifically designed for motocross, this RFX Pro Series Armalite composite sprocket combines a CNC machined 7075-T6 aluminum hub and a high carbon steel (HCS) outer ring. The result is a lightweight part that maintains a durable support face for the teeth, ideal for riders seeking reliability and grip on demanding terrains.

Pitch diameter 420 compatible with 420 transmission
56 teeth
CNC machined 7075-T6 aluminum inner ring
HCS outer ring for better tooth durability
Hex-Drive interface between the two rings for a positive connection and reduced stress on the rivets
Optimized CAD profile, mud evacuation grooves, and red anodization

The double ring design limits unsprung mass and preserves the longevity of the outer sprocket. Supplied with detailed installation instructions, this model fits 420 transmissions and is particularly suitable for machines like the Honda CRF 150 R (models 2020 to 2026 depending on configuration). For replacement, always check compatibility with your hub and adhere to the manufacturer's torque specifications.
