RFX Motorcycle crown Honda Pro Series 520 Honda CRF 450 R (PE07)

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

The dual sprocket design provides optimal performance, reduced weight thanks to a centre made of 7075-T6 aluminium, and longer life for the teeth due to the outer layer of high-density carbon steel.

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

Features:

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