It is recommended to use 10W-30 or 10W-40 motorcycle oil that meets or exceeds the MA standard. Always check the owner’s manual for any updates or specific requirements.
The oil should be changed every 100 hours of operation or at least once a year, whichever comes first. Regular maintenance ensures optimal performance.
The recommended tire pressure for the front tires is 4.4 psi and for the rear tires is 3.6 psi. Always consult the owner's manual for confirmation.
Start by checking the battery connections and fuses. Ensure all connections are clean and tight. If the issue persists, consult a professional mechanic.
Check the fuel level, battery charge, and make sure the kill switch is not engaged. If these are in order, inspect the spark plug and fuel line for blockages.
Regularly check and change the transmission fluid as per the maintenance schedule. Inspect for leaks and ensure the gearshift operates smoothly.
Use a high-quality ethylene glycol-based antifreeze that is specifically designed for aluminum engines. Always ensure the coolant system is free of leaks.
Remove the air filter cover and take out the filter. Use compressed air to clean it if it’s not too dirty, or wash it with a mild detergent and let it dry completely before reinstalling.
Common causes include low coolant levels, clogged radiators, or a malfunctioning thermostat. Regular maintenance and checks can prevent overheating.
Maintain proper tire pressure, perform regular maintenance, ensure the air filter is clean, and avoid aggressive acceleration to improve fuel efficiency.
