Warning
The headlight might fog up due to washing, rain
or moisture. Switch headlight on for a short time to
help and dry up any condensate.
Carefully clean the phonic wheels of the ABS in order
to ensure system efficiency. Do not use aggressive
products in order to avoid damaging the phonic
wheels and the sensors.
Note
To clean the instrument panel do not use alcohol
or its by-products.
Pay special attention when cleaning the wheel rims
since they have parts in machined aluminium; clean
and dry them every time you use the motorcycle.

Warning
To clean the side panniers, sue warm water,
neutral soap and a soft cloth. Soap and soft brushes
are suitable to clean the zips; rinse them with clean
water. Do not use aggressive detergents and too hard
cleaning tools. Zips that prove hard to be moved can
be loosened using a bit of talcum powder.
