RFX Motorcycle crown Gas Gas Pro Series 520

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

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

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

Features:

• CNC machined 7075 aluminium inner ring
• HCS outer ring
• Hex-Drive location between the inner and outer rings
• CAD-designed profile for reduced weight.
• New mud release groove style to decrease wear.
• The rigid design increases torsional strength.
• Anodised colour
