WHEELS AND TIRES

Carefully read PRECAUTIONS AND GENERAL
INFORMATION.

CHECKING THE WHEELS

Make sure that the wheel rims are neither cracked nor
deformed. Replace if necessary.
Check the wheel eccentricity.
If it is deformed beyond tolerance limits, check the rim
and the bearings.
Replace the wheel if necessary.
Eccentricity limits:
Vertical: 0.078 in (2 mm)
Lateral: 0.078 in (2 mm)
Check the wheel balancing.
Rotate the wheel slowly several times and observe
the position in which it stops.
If the wheel is not statically balanced, it will always
stop in the same place. Place a balancing weight on
the lightest point of the wheel (top).
TIRES
This vehicle is equipped with tubeless tires (no inner
tube).
WARNING
Periodically check the inflation pressure of the
tires at ambient temperature, see (TECHNICAL
SPECIFICATIONS).
If the tires are warm, the measurement will not be
correct.
Always measure before and after any long trips.
If the inflation pressure is too high, the shocks of
rough terrain are not absorbed and are transmit-
ted to the handlebars, making for an uncomfort-
able ride and also diminishing the vehicle's ability
to adhere to curves.
