TIP
Air lter
• This model's air lter is equipped with a disposable oil-coated paper element, which must not be cleaned with com-
pressed air to avoid damaging it.
• The air lter element needs to be replaced more frequently when riding in unusually wet or dusty areas.
V-belt case air lter
• The air lter needs more frequent service if you are riding in unusually wet or dusty areas.
V-belt
• The V-belt should be checked at the initial 8000 km (5000 mi) and every 4000 km (2500 mi) thereafter. Replace the
V-belt if any damage or excessive wear is found. The V-belt needs to be replaced every 25000 km (15500 mi) even
if there is not wear or damage.
Hydraulic brake service
• Regularly check and, if necessary, correct the brake uid level.
• Every two years replace the internal components of the brake master cylinders and calipers, and change the brake
uid.
• Replace the brake hoses every four years and if cracked or damaged.
Fuel system service
• Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts, such as
the valves and piston rings, as well as to the exhaust system.
• Replace the fuel ller cover every two years or if cracked or damaged.
• Check the fuel lter for clogging or damage every 12000 km (7500 mi).
Battery service
• Check the condition and service the battery every 3 months.
• Recharge the battery immediately if the voltage is less than 12.7 V.
• If the battery tends to discharge, replace it immediately.
