SCOOTER! Operation of an
overloaded scooter may result
in tire damage, loss of control,
or severe injury. Make sure that
the total weight of rider, cargo,
and accessories does not ex-
ceed the specified maximum
load for the vehicle.
●
Improper tire air pressure great-
ly affects tire life and handling.
●
If the tire air pressure is too
high, shocks from the road will
not be dampened but instead be
transmitted to the frame and
handlebars, which impairs
riding comfort. 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 addi-
tion, the tires could slip off the
wheel rims during braking,
which could result in tube dam-
age. The scooter could also eas-
ily turn over in a curve.
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.
Tire information
This scooter is equipped with panel
wheels and tubeless tires.
