RFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 SprocketRef : RFX00287A / 1123218003

Reference : FXRS 10-50 ALRD — RFX Pro Series Armalite Sprocket 520, 50 teeth, red color.

Designed for off-road demands, this double composite Armalite sprocket combines a machined core made of 7075-T6 aluminum and a high-carbon content HCS outer ring. The result: a lightweight assembly that does not compromise the resistance of the teeth against abrasion and track stresses.

The "double ring" architecture incorporates a Hex-Drive interface between the inner and outer rings, a solution that enhances torque transmission between the parts and reduces the load borne by the rivets. The CAD profile optimizes mass and rigidity to limit torsion, while the new mud evacuation grooves help reduce clogging and wear in muddy conditions.

• Materials : CNC 7075 aluminum core / HCS outer ring.
• Pitch : 520 — suitable for standard cross transmissions.
• Teeth : 50 teeth — versatile choice for balancing acceleration/top speed.
• Finish : red anodization for protection and race look.
• Design : Hex-Drive for better cohesion between inner/outer ring.

Ideal for motocross and enduro riders looking for a robust, lightweight sprocket designed for tough conditions. Check compatibility with your model and follow manufacturer installation recommendations for safe replacement.
