RFX Motorcycle crown Kawasaki Pro Series 520 KX 125 (KX125B)

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
