TIP


Engine air filters and V-belt air filter

This model’s engine air filters are equipped with disposable oil-coated paper elements, which must not be cleaned
with compressed air to avoid damaging them.

The engine air filter elements need to be replaced and the V-belt air filter element needs to be serviced more frequent-
ly when riding in unusually wet or dusty areas.

Hydraulic brake service

Regularly check and, if necessary, correct the brake fluid level.

Every two years replace the internal components of the brake master cylinders and calipers, and change the brake
fluid.

Replace the brake hoses every four years and if cracked or damaged.
