Product details :

Features

Manufacturer Reference: FXRS10-52ALBK

The RFX Pro Series Armalite 520 - 52 teeth sprocket combines lightweight and robustness for off-road use. Developed by racing teams (world and British championships), it features a CNC machined 7075-T6 aluminum core and a high carbon density HCS outer ring. This double-ring construction reduces rotating weight while extending the lifespan of the teeth, specially designed to withstand the demands of motocross.

Type: RFX Pro Series Armalite double composite sprocket
Materials: 7075 aluminum center (CNC) / HCS outer ring
Number of Teeth: 52
Chain Pitch: 520
Finish: black anodization
Technology: Hex-Drive interface between inner and outer ring for optimized transmission without stress on the rivets
Design: lightweight CAD profile, mud grooves, and rigid design against twisting

Designed to withstand tough terrain conditions (jumps, aggressive trajectories, debris), this sprocket is aimed at demanding motocross and enduro riders. Follow the manufacturer's installation recommendations and torque specifications when replacing the rear wheel and chain. Compatibility: 520, 52 teeth — recent Honda CRF 450 models (R / RX / RWE) among others.
