Introduction
Over time, due to excessive sitting or wear, wheel bearings develop flat spots and lose lubrication causing poor performance, and if left untreated, failure. The purpose of this guide is to walk the user through the process of replacing the wheel bearings on a typical motorcycle wheel using a wheel from a 1996 Honda CBR900RR FireBlade.
You will need a few tools, some new wheel bearings and seals, some paper towels, and a good wheel bearing grease.
What you need

On the left side of the motorcycle, use the 12 mm wrench to remove the bolts in the order indicated.
-
On the right side, use the 12 mm wrench to remove the first two bolts, the 22 mm wrench for the third, and finish up with the 12 mm on the remaining two.
