Maintenance and Adjustment
Warning
Do not install tube-type tires on tubeless
rims. The bead will not seat and the tires
could slip on the rims, causing rapid tire
deflation that may result in a loss of vehicle
control and an accident. Never install an
inner tube inside a tubeless tire. This will
cause friction inside the tire and the
resulting heat build-up may cause the tube
to burst resulting in rapid tire deflation, loss
of vehicle control and an accident.

Warning
Inner tubes must only be used on
motorcycles fitted with spoked wheels and
with tires marked 'TUBE TYPE'.
Some brands of approved tire marked
'TUBELESS' may be suitable for use with
an inner tube. Where this is the case, the
tire wall will be marked with text
permitting the fitment of an inner tube (see
illustration below).
Use of an inner tube with a tire marked
'TUBELESS', and NOT marked as suitable
for use with an inner tube, or use of an
inner tube on an alloy wheel marked
'SUITABLE FOR TUBELESS TIRES' will
cause deflation of the tire resulting in loss
of motorcycle control and an accident.
