RFX Pro Series Axle Blocks are designed to speed up and improve wheel changes with easy fitting and more precise alignment.
RFX FXAB 40300 99RD rear axle blocks are engineered for Yamaha YZ250F and YZ450F models from 2014 to 2018, providing rapid wheel changes and precise alignment.
Constructed from CNC-machined 7075 aerospace aluminum, these axle blocks feature a CAD-designed profile that reduces weight while maintaining strength. The laser-etched RFX logo adds a factory-style appearance, and the anodized finish offers corrosion resistance and a clean look. The tighter tolerances ensure a secure fit, simplifying maintenance and assembly.
This kit includes two axle blocks, each designed for easy installation with one spanner on one side, allowing for quick adjustments and reduced downtime during wheel swaps. The color anodized surface enhances the bike's aesthetic, matching factory components for a cohesive appearance. These axle blocks are an essential upgrade for riders seeking efficient wheel changes and consistent alignment on Yamaha YZ250F and YZ450F models between 2014 and 2018.
