weight of rider, passenger, car-
go, and accessories approved
for this model.

WARNING

EWA10512

Never overload your vehicle. Opera-
tion of an overloaded vehicle could
cause an accident.

Tire inspection

The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.

TIP

The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.

WARNING

EWA10472

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.

The replacement of all wheel
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience to do so.

Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimal
characteristics.

Cold tire air pressure:

1 person:

Front:

250 kPa (2.50 kgf/cm², 36 psi)

Rear:

290 kPa (2.90 kgf/cm², 42 psi)

2 persons:

Front:

250 kPa (2.50 kgf/cm², 36 psi)

Rear:

290 kPa (2.90 kgf/cm², 42 psi)

Maximum load:

Vehicle:

162 kg (357 lb)

The vehicle’s maximum load is the 
combined weight of the rider, pas-
senger, cargo, and any accessories.

1. Tire sidewall
2. Tire tread depth

Minimum tire tread depth (front and 
rear):

1.5 mm (0.06 in)
