RFX Pro Series Elite Aluminum Sprocket - 428 (FXRS 35-52 99BU)
Designed for motocross riding, the RFX Pro Series Elite sprocket combines lightweight and durability to withstand the demands of heavy terrain. CNC machined from 7075 aluminum and anodized blue, it features an optimized CAD profile and tight tolerances for precise engagement with your 428 chain. The mud drainage grooves extend the lifespan of both the chain and sprocket in muddy conditions.
Ideal for riders looking for a lightweight and durable sprocket for their off-road sessions, it is particularly suitable for the listed 85cc machines (YAMAHA YZ 85, YZ 85 LW Big Wheels, SUZUKI RM 85). Note: please check the exact compatibility with your model and spacer before installation. Choose RFX for a drive component designed for the terrain and intensive maintenance.
