proved the wheels and tyres
it cannot assess their suita-
bility or provide any guaran-
tee of road safety. You can

Accessories and loads
d Warning:
BMW cannot examine or test
each product of outside origin
on the accessories and tyres
market to ensure that it can be
used on or in connection with
BMW motorcycles without con-
stituting a safety hazard. Even
approval by an official inspec-
tion authority or an official per-
mit (General Operating Permit)
cannot always provide this
guarantee. Tests conducted by
these instances cannot make
provision for all operating condi-
tions experienced by BMW mo-
torcycles and consequently,
they are not sufficient in some
circumstances.
\f Note:
BMW accessories and other
products approved by BMW
can be obtained from your
authorised BMW motorcycle
dealer.
