Body style and inspection points

On a motorcycle, tyres, final drive and brakes matter as much as the oil change. Check the tyre manufacturing date, steering-head play and fork-tube seals; an oil film on a tube means a fork seal needs replacing. A notched steering bearing can be felt when braking at low speed.

Maintenance and records

≈: estimated reference — the vehicle’s service indicator prevails.

Oil and filter change

≈ 10,000 km or 1 year

JASO MA or MA2 approved four-stroke motorcycle oil (JASO MB on scooters): an “energy conserving” car oil makes the wet clutch slip. Change it more often in city use or on track.

Brake fluid

Every 2 years

Replace the fluid in both circuits (and the hydraulic clutch if fitted), whatever the mileage; dark fluid has absorbed moisture.

Source [1]

Fork oil

≈ 30,000 km

Fork oil change and seal check; an oil film on the tubes means a seal needs replacing before it contaminates the brake caliper.

Source [1]

Chain kit (chain and sprockets)

≈ 25,000 km

Lubricate and check the tension every 500 to 1,000 km and after rain; replace chain and sprockets together when the chain no longer holds its tension or the teeth are hooked.

Source [1]

Spark plugs

Every 20,000 km

Replace the full set; worn plugs raise consumption and cause misfires.

Source [1]

Air filter

Every 40,000 km

Replace more often in dusty conditions.

Source [1]

Valve clearance

Every 40,000 km

Check and adjust if needed, often together with the plugs; too little clearance burns the valves, too much makes the engine noisy.

Source [1]

Coolant

Every 3 years

Replace the coolant and check the hoses and radiator; check the level cold between services.
