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

Product details :

Features

RFX Pro Series Armalite – Ref. FXRS 15-55 ALRD

Two-piece composite sprocket designed for off-road and motocross. The Armalite design combines a CNC machined core made of 7075-T6 aluminum and a high carbon steel (HCS) outer ring to minimize weight without sacrificing tooth strength. Tested by racing teams, it offers a useful compromise between responsiveness and durability for demanding riders.

Type: RFX Pro Series double sprocket
Number of teeth: 55
Chain pitch: 420
Materials: 7075-T6 aluminum inner ring (CNC) / HCS outer ring
Interface: Hex-Drive between inner and outer ring to maximize transmission and reduce stress on the rivets
Design: Lightweight CAD profile, mud evacuation grooves, and red anodized finish

Simple installation: follow the manufacturer's manual for torque specifications, clean the hub, position the sprocket, apply a threaded locking compound (Loctite recommended), and check the chain alignment. Suitable for HONDA CRF 150 R (2020-2026) and Big Wheels / STD Wheels derivatives in 420.
