- Remove the fork tubes, making sure that you secure the clip- on’s and the wiring
- Remove the Top Clamp by first removing the nut

Bearing Removal

- pry open the locking tabs
- remove the locknut below the “T” clamp
- undo the but while carefully holding the Lower T from below the steering column
- careful so as to not drop it
- now remove the dust seal and you will see the bearings under that
- remove the bearings and upper inner race and wipe off the grease from the upper and lower races both within the steering column
- hit out the races with a drift and hammer carefully
- take off the lower bearing and lower inner race from the lower T which you removed earlier (this race may be a tight fit and will take some effort to remove)
- remove the lower dust seal


- first install the outer upper and lower races within the steering column..gently tapping them into place using the old races as a damper between the new races and hammer.
- install the lower dust seal, inner lower race and then the lower bearing after smearing both the race and bearing with grease liberally
- now smear the upper race with grease and lube and place the upper bearing on the race
- gently guide the lower race through the steering stem
- place the upper dust seal over the upper bearing
- install the cover, top nut and bend the locking tabs in place
- fit the top clamp and the top retaining nut.
- Fit the forks, wheel and tighten everything
- Move the handle from side to side about 6 times to settle the bearings

Note - The bearing sizes and part numbers are same across the CBR range from the 250 right upto the 954.[hr]

Thread revival but just wanted to say I bought the above mentioned all balls kit and the lower inner race is the wrong size and doesn't fit on the stem. Heads up.
I should add that the bearing is the correct part number and should fit on there. But is way too small it won't even fit just past the threads at the top of the stem let alone on the fatter part at the bottom.
which is the incorrect number?

Do you have the correct part number? thanks for the heads up
