Product details :

Features

RFX Pro Series Armalite Sprocket 51 Teeth - FXRS20-51ALBK

Specifically designed for motocross, this Armalite sprocket combines lightweight and durability thanks to a bi-material construction: a CNC machined hub made of 7075 aluminum and an outer ring made of HCS steel. The dual-ring concept limits unsprung mass and maintains a tooth profile that withstands the demands of muddy terrain.

Type: Dual sprocket (Armalite) - 51 teeth
Pitch: 520
Material: 7075-T6 aluminum hub / HCS outer ring
Finish: Black anodized
Technical features: Hex-Drive interface between inner and outer ring to reduce load on the rivets, CAD-optimized profile for weight reduction, mud clearance grooves

The rigid design limits twisting under load, and the clearance grooves reduce mud accumulation for more even wear on the teeth. Simple installation by following the procedure and torque specifications: cleaning the hub, positioning, applying Loctite, and uniformly tightening the fasteners.

Compatibility: intended for motocross machines (e.g., KAWASAKI KX 450 X / KX 250 X / KX 250 2026 listed among common models). Always check the pitch and number of teeth before installation.
