RFX Motorcycle crown Honda CRF 450 RX ENDURO (PE07) [450]

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

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

The Armalite sprockets also feature a hexagonal interface between the inner and outer rings, a groundbreaking technology for sprockets that maximises the transmission between the two parts and eliminates all 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 lightweight.
• New mud clearance groove style to reduce wear.
• The rigid design increases torsional strength.
• Anodised colour
