Using a dial gauge, check the wheel pin «2» ec-
centricity. Replace the pin «2» if the eccentricity
exceeds the limit value.
Characteristic
Maximum eccentricity:
0.25 mm
WHEEL RIM
Using a dial gauge, check that the radial eccen-
tricity «A» and the axial eccentricity «B» of the
wheel rim «3» do not exceed the limit value.

replaced, the value is not within the specified limit.

TYRES
Every month check that the tyres are in good con-
ditions. Check tyre pressure mainly before and
after a long trip. Check tyre inflation pressure every
month at ambient temperature. This vehicle is fit-
ted with tyres without inner tubes (Tubeless).
CAUTION
CHECK TYRE TREAD FOR WEAR. BADLY WORN TYRES
COMPROMISE TRACTION AND HANDLING.
REPLACE TYRES WHEN WORN OR IF THERE IS A PUNC-
TURE BIGGER THAN 5 MM IN THE TREAD.
SOME TYRE TYPES HOMOLOGATED FOR THIS SCOOT-
ER FEATURE WEAR INDICATORS.
THERE ARE SEVERAL TYPES OF WEAR INDICATORS.
CONSULT YOUR DEALER ON METHODS TO CHECK
WEAR. DO NOT FIT TYRES WITH INNER TUBES ON RIMS
FOR TUBELESS TYRES OR VICE VERSA.
CHECK THAT THE INFLATION VALVES «1» HAVE THEIR
CAPS FITTED IN ORDER TO AVOID UNEXPECTED FLAT
TYRES. REPLACEMENT, REPAIR, MAINTENANCE AND
BALANCING OPERATIONS ARE VERY IMPORTANT; THEY
SHOULD BE CARRIED OUT WITH SUITABLE TOOLS BY
QUALIFIED PERSONNEL.
