RFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 SprocketRef : RFX00411A / 1123236006

RFX Pro Series Armalite 520 Sprocket - 49 Teeth (Manufacturer Part No: FXRS 50-49 ALRD)

Designed for the demanding terrains of motocross, quads, and sharp roadsters, this RFX Armalite double composite sprocket combines lightweight construction with durability. The CNC machined inner hub made from 7075-T6 aluminum reduces rotational weight for a more responsive performance, while the outer ring made from high-density HCS steel ensures increased tooth resistance against wear.

• Number of teeth: 49 (pitch 520)
• Construction: 7075-T6 aluminum inner ring + HCS outer ring
• Hex-Drive interface between the two rings to optimize torque transmission and minimize stress on the rivets
• CAD profile and mud evacuation grooves to limit clogging and abrasion
• Color: anodized red, durable finish

The rigid design limits torsion under heavy load, and standard dimensions facilitate replacement. Simple installation as a standard replacement: adhere to the specified torque and manufacturer recommendations, use appropriate Loctite, and check chain alignment and tension after installation.

Main compatible motorcycles (examples): TRIUMPH TF 450-X, DUCATI DESMO 450 MX, STARK FUTURE VARG EX.
