RFX Motorcycle crown Honda Pro Series 520 CRF 250 R (ME12)

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

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

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

Features:

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