TIP
Engine air filter and V-belt air filters
• This model’s engine air filter is equipped with a disposable oil-coated pa-
per element, which must not be cleaned with compressed air to avoid
damaging it.
• The engine air filter element needs to be replaced and the V-belt air filter
elements need to be serviced more frequently when riding in unusually wet
or dusty areas.
Hydraulic brake service
• After disassembling the brake master cylinders and calipers, always
change the fluid. Regularly check the brake fluid levels and fill the reser-
voirs as required.
• Every two years replace the internal components of the brake master cyl-
inders and calipers, and change the brake fluid.
• Replace the brake hoses every four years and if cracked or damaged.
