PERIODIC MAINTENANCE AND MINOR REPAIR
shocks from the road will not be
dampened but instead be trans-
mitted to the frame and handle-
bars, which impairs riding com-
fort. In addition, the scooter will
be unstable in curves.
If the tire air pressure is too low,
the tires will be damaged and the
tire life shortened. In addition, the
tires could slip off the wheel rims
during braking, which could re-
sult in tube damage. The scooter
could also easily turn over in a
curve.
Tire air pressure* (measured on cold
tires):
Front:
150 kPa (22 psi) (1.50 kgf/cm
2
)
Rear:
175 kPa (25 psi) (1.75 kgf/cm
2
)
Tire inspection
Always check the tires before operating
the scooter. If a tire tread shows cross-
wise lines (minimum tread depth), if the
tire has a nail or glass fragments in it,
or if the sidewall is cracked, contact a
Yamaha dealer immediately and have the
tire replaced.
Minimum tire tread depth (front and
rear):
1.0 mm (0.04 in)

The replacement of all wheel- and
brake-related parts, including the

dealer, who has the necessary
professional knowledge and ex-
perience.
