This model is equipped with tubeless
tires and tire air valves.
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.
WARNING
 The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motorcy-
cle may be different, which
could lead to an accident.
 Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.
 Use only the tire valves and
valve cores listed below to
avoid tire deflation during a
high-speed ride.
