Tire Air Pressure
Tire air pressure affects traction, handling, and tire
life. Adjust the tire air pressure to suit track condi-
tions and rider preference, but keep it close within
the recommended range.
•
To check the tire air pressure, remove the air valve
cap, and make sure to tighten the cap securely
after checking the tire pressure.
•
Reduce the tire air pressure to increase the tire
tread surface on the ground when riding on a wet,
muddy, sandy or slippery track.
•
Increase the tire air pressure to prevent damage
or punctures (though the tires will skid more easily)
when riding on a pebbly or hard track.
Tire Air Pressure Adjustable Range

NOTE
○
Tire air pressure should be checked when the tires
are cold, before you ride the motorcycle.
Spokes and Rims
The spokes on both wheels must all be securely
and evenly tightened and not be allowed to loosen.
Unevenly tightened or loose spokes will cause the
rim to warp, the nipples and spokes to fatigue more
quickly, and the spokes to break.

Bead Protector
There is a bead protector nut on the both wheels.
The bead protector nut prevents the tire and tube
from slipping on the rim and damaging the valve
stem. Valve stem damage may cause the tube to
leak, necessitating tube replacement. In order to
keep the tire and tube in position on the rim, inspect
the bead protector nut before riding and tighten it if
necessary. Tighten the valve stem nut finger tight
only.
