INSPECTION

Turn the inner race of each bearing with your finger.

The bearings should turn smoothly and quietly. Also check that the bearing outer race fits tightly in the hub.

Replace the bearings if they do not turn smoothly, quietly, or if they fit loosely in the hub.

Inspect the following parts for damage, abnormal wear, deformation or bend.

• Front axle
• Wheel hub
• Wheel rim

Measure each part according to FRONT WHEEL/ SUSPENSION/STEERING SPECIFICATIONS.

Replace any part if it is out of service limit.

DISASSEMBLY/ASSEMBLY

Disassemble and assemble the front wheel as following illustration.

• Install each dust seal with the flat side facing out so that it is flush with the wheel hub.
• Install the brake disc with the rotation mark (arrow) facing out.

WHEEL BALANCE

NOTE:

• Mount the tire with the arrow mark [1] facing in the direction of rotation.
• For optimum balance, the tire balance mark [2] (light mass point: a paint dot on the side wall) must be located next to the valve stem [3]. Remount the tire if necessary.
• The wheel balance must be checked when the front tire is remounted.
• Stick-type balance weights should be used on this motorcycle. Use genuine Honda balance weights.
  • Before installing the weights, remove any adhesive from the rim thoroughly and clean the area where new weights are to be placed with degreasing agent. Take care not to scratch the rim surface.
  • Do not touch the adhesive surface of the weight with your bare hands when installing.
  • The balance weights are always replaced with new ones whenever they are removed. Do not reuse them.

Mount the wheel, tire and brake disc assembly on an inspection stand [1].

Spin the wheel, allow it to stop, and mark the lowest (heaviest) part of the wheel with chalk.

Do this two or three times to verify the heaviest area.

If the wheel is balanced, it will not stop consistently in the same position.

To balance the wheel, install the wheel weights [1] on the highest side of the rim, on the side opposite the chalk marks. Add just enough weight so the wheel will no longer stop in the same position when it is spun.

Do not add more than 60 g (2.1 oz) to the wheel.

Press the weights by your hands firmly and make sure they are not come off the rim.

NOTE:

• The weights are attached to the position at 8 mm (0.3 in) from the side surface of the rim in the direction as shown.
• If the weight exceeds 10 g (0.4 oz), install same amount of the balance weights on the right and left symmetrical position.
