RFX Pro Series Armalite Double Compound (Steel/Aluminium) - 520 SprocketRef : RFX00321A / 1123223001

RFX Armalite Pro Series Sprocket - Ref. FXRS 20-48 ALGN

Designed for demanding off-road conditions, this RFX Armalite double composite sprocket combines lightweight and durability for motocross. Its machined core made from 7075-T6 aluminum reduces unsprung mass while the high carbon density steel outer ring protects the teeth against abrasion and repeated loads on muddy trails or tracks.

The exclusive Hex-Drive technology ensures a solid interface between the inner ring and the outer ring, limiting the stresses transmitted to the rivets and improving the torsional rigidity of the assembly. The CAD profile optimizes mass without sacrificing strength, and the mud clearance grooves facilitate debris evacuation to reduce wear in dirty conditions.
