Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.

Spoke wheels
To maximize the performance, durabil-
ity, and safe operation of the vehicle,
note the following points.
Check each wheel for cracks, de-
formation and other damage. If
any damage is found, have the
wheel inspected by your Yamaha
dealer. Do not attempt to repair or
straighten a bent or damaged
wheel.
Check the spokes for looseness. If
any loose spokes are found, have
the wheel adjusted by your
Yamaha dealer. Improperly tight-
ened spokes can cause wheel
misalignment.
Have the wheel balanced whenev-
er the tire or tube has been re-
placed. An unbalanced wheel can
result in adverse handling charac-
teristics and shortened tire life.
