Bushings & Spacers

Motorcycle Wheel Bushings and Spacers

The wheel bushings and spacers position the wheel and hub in relation to the fork or swingarm, provide proper axle support, and prevent excessive lateral loads on the bearings. They are installed with bearings, seals, and clamping surfaces, so an incorrect measurement can cause play, misalignment, or poor wheel rotation.

Compatibility must be verified for the specific motorcycle, axle, wheel, and hub. Front and rear parts are generally not interchangeable, and the left and right sides may use different lengths, diameters, or recesses. If the hub or wheel has been changed from the original configuration, check the entire assembly rather than choosing parts based only on the motorcycle model.

Spacer Dimensions and Installation

• Inner diameter: must match the axle without abnormal play or requiring force to install.
• Outer diameter: must seat against the seal, bearing, or intended housing.
• Length: determines the wheel's centering and lateral position between the support points.
• Location: confirm whether it fits the front or rear assembly and which side of the hub it belongs on.
• Geometry: compare flanges, recesses, and contact faces with the removed part.

Before installation, measure the parts with calipers, inspect the bearings and seals, and retain the original order. After tightening the axle to the torque specified for the motorcycle, make sure the wheel spins freely, remains aligned, and has no play or contact with the brake or suspension.
