RFX Motorcycle crown Suzuki RMX 450 Pro Series 520

The RFX Pro Series Armalite sprockets are designed and tested at the highest level by the racing teams of World and British championships.

The dual sprocket design offers optimal performance, reduced weight thanks to a 7075-T6 aluminium centre, and longer tooth lifespan due to the outer made of high-density carbon steel.

The Armalite sprockets also feature a hexagonal interface between the inner and outer rings, a revolutionary technology for sprockets that maximises transmission between the two parts and reduces the force exerted on the rivets to zero.

Features:

• 7075 CNC aluminium inner ring
• HCS outer ring
• Hex-Drive location between the inner and outer rings
• CAD designed profile for lightweight.
• New style mud clearance grooves to reduce wear.
• Stiff design increases torsional strength.
• Anodised colour
