Cleaning the motorcycle
To preserve the finish of metal parts and paintwork, wash
and clean your motorcycle at regular intervals, anyway
according to the road conditions you ride in. Use specific
products only. Prefer biodegradable products. Avoid
aggressive detergents or solvents.
Important
Do not wash your motorcycle right after use. When
the motorcycle is still hot, water drops will evaporate
faster and spot hot surfaces.
Never clean the motorcycle using hot or high-pressure
water jets. Cleaning the motorcycle with water cleaners
may lead to seizure or severe failure of front fork, wheel
hub assembly, electric system, front fork seals,
air inlets or exhaust silencers and adversely affect the
operation of motorcycle safety features
Clean off stubborn dirt or exceeding grease from engine
parts using a degreasing agent. Be sure to avoid contact
with drive parts (chain, sprockets, etc.)
Rinse with warm water and dry all surfaces with chamois
leather.
Warning
Braking performance may be impaired immediately
after washing the motorcycle.
Never grease or lubricate the brake discs. Loss of braking
and further accidents may occur.
Clean the discs with an oil-free solvent.
