CHECKING THE BEARINGS CLEARANCE
To check the steering, it is necessary to:
- Position the vehicle on the centre stand.
- Place a support under the motorcycle in such a way that the front wheel is able to move freely and
the vehicle does not fall.
When carrying out this operation, pay attention not to mistake the centre stand clearance with that of
the steering. Repeat this test many times before deciding if the steering clearance must be adjusted.
- Hold the fork sleeves and pull the fork forwards and backwards, with the steering in forward position.
- There should be no clearance forward or backward If there is clearance, the steering must be adjusted.
ADJUSTING THE BEARING CLEARANCE
- Remove the handlebar.
- Loosen the upper ring nut «1» using the specific
wrench.
- Screw in the lower ring nut «3» until the bearing
clearance is totally eliminated.
CAUTION
DO NOT EXCESSIVELY TIGHTEN THE LOWER RING NUT
«3» BECAUSE THE STEERING BEARINGS COULD GET
DAMAGED.
- Check clearance as described above. Make sure the front fork can move all long its stroke, from left
to right or vice versa, rotating freely and smoothly.
- Keep the lower ring nut «3» in position, by using a specific wrench and tighten the upper ring nut «1»
to the specified torque. Check again the bearings clearance.
