RFX Pro Rear Wheel Spacers (Blue) – Yamaha YZF250/450

Machined spacers for motocross riders who want reliability and finish on their YZF 250/450. Made from high-strength aluminum and anodized, these spacers replace the original parts while providing a precise fit for quick and play-free installation.

• Material: 7075-T6 aluminum, lightweight and durable.
• Finish: Blue anodization to minimize surface wear and reduce dirt adhesion.
• Machining: CNC for tight tolerances and reliable positioning in the hub.
• Design: Machined rear lip to keep the spacer in the seal during maintenance.
• Compatibility: Yamaha YZF 250 / 450 (see motorcycle reference).
• Manufacturer part number: FXWS4060099BU

These spacers facilitate common operations (wheel removal/reinstallation, seal cleaning, lubrication) thanks to their design that keeps them in place during interventions. The precise fit limits lateral stress on the axle and aids in the correct positioning of the hub and chain. Follow the torque specifications and manufacturer recommendations during reassembly to ensure safe operation.
