RFX Pro Rear Wheel Spacers (Blue) ā FXWS4050099BU
Designed for demanding motocross riders, these RFX Pro series spacers combine strength and meticulous finishing. Machined from 7075-T6 aluminum and then anodized in blue, they offer high wear resistance while minimizing dirt buildup around the hub and seals. Their profile features a machined rear lip that keeps the spacer in place during disassembly, simplifying and securing the wheel change in the workshop or paddock.
Maintenance tips: clean the contact surfaces and seals, apply a thin layer of grease under the seal during reassembly, and check the axle tightness as well as chain tension after installation. RFX products are tested and used by several Grand Prix and British motocross teams, ensuring a competition-oriented finish.
