Maintenance
Typical interval: oil change every 10,000 km or 12 months, whichever comes first. Brake fluid every 2 years. On chain-driven models, lubricate and adjust the chain every 500 to 1,000 km. Plugs, valve clearance and air filter depend on the engine: see each version.
Body style and inspection points
On a scooter, have the variator belt and rollers checked when due, even if the scooter covers little distance in town. Also check the small-diameter tyres, which wear fast, the lights and the centre stand; a slipping belt is felt when pulling away.
