Engine air filter and V-belt air filter
This models engine air filter is equipped with a disposable oil-coated paper 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 element needs to be ser-
viced 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.
