Maintenance Fundamentals
Tyres (Inspecting/Replacing)
#
Checking the Air Pressure
Visually inspect your tyres and use an air
pressure gauge to measure the air pressure at
least once a month or any time you think the
tyres look low. Always check air pressure when
your tyres are cold.
Even if the direction of the valve stem is
changed, do not return it to the original
position. Have your motorcycle inspected by
your dealer.

the side walls of the tyres.

Inspecting Tread Depth
Inspect the tread wear indicators. If they
become visible, replace the tyres immediately.
Inspect the tyres for
cuts, slits, or cracks that
exposes fabric or
cords, or nails or other
foreign objects
embedded in the side
of the tyre or the tread.
Inspect the tyres for
signs of abnormal wear
on the contact surface.
