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.
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]Shaft drive
≈ 20,000 km
At each service: final-drive seal tightness, rear-wheel play and final-drive oil level or change as listed in the bike’s service book.
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 20,000 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.
