TIP
Air filter and V-belt filter
This model’s air filter is equipped with a disposable oil-coated paper elemen t, which must not be cleaned with com-
pressed air to avoid damaging it.
The air filter element needs to be replaced and V-belt filter needs to be serviced more frequently when riding in un- usually wet or dusty areas.

Hydraulic brake service
After disassembling the brake master cylinder and caliper , always change the fluid. Regularly check the brake fluid
level and fill the reservoir as required.
Every two years replace the internal components of the brake master cylinder and caliper, and change the brake fluid. Replace the brake hose every four years and if cracked or damaged.
