Air filter

This model’s air filter is equipped with a disposable oil-coated paper element, which must not be
cleaned with compressed air to avoid damaging it.

The air filter element needs to be replaced 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 reservoirs as required.

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.
