WHEELS AND TYRES

Read through the paragraph PRECAUTIONS AND
GENERAL INFORMATION.

WHEELS INSPECTION

Check that the wheel rims are not cracked or dis-
torted. If necessary replace them.
Check the radial runout of the wheel.
If the wheel is distorted beyond the acceptable limit,
check the condition of the rim and the bearings.
If necessary replace the wheel.
Runout limits:
Vertical runout: 2 mm (0.078 in)
Lateral runout: 2 mm (0.078 in)
Check the wheel trim.
Slowly turn the wheel several times and observe the
point at which it stops.
If the wheel is not statically balanced, it will always
stop at the same point. Fit a balancing weight at the
lightest point (top).

TYRES

Read through the paragraph PRECAUTIONS AND
GENERAL INFORMATION.
This vehicle is provided with tubeless tyres.
WARNING
Periodically check the tyre inflation pressure at
room temperature, see (TECHNICAL DATA).
If the tyres are hot, the measurement is not correct.
Carry out the measurement especially before and
after long rides.
If the inflation pressure is too high, the ground
unevenness cannot be dampened and is therefore
transmitted to the handlebar, thus compromising
the driving comfort and reducing road holding
during turns.
