RFX Motorcycle crown Aprilia SXV 450 Pro Series 520

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

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

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

Features:

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