AutoKarnet advice
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.

Comparing generations
Other documented generations of this model: • PCX 125 (2018) (2018–2020) : scooter, 12–12 hp. A first registration near a generation change does not identify the car on its own: check the body style and powertrain before using a service schedule.

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]Final drive oil
≈ 20,000 km
The rear-wheel gearcase has its own oil, separate from the engine oil; replace it when the service book says, often with the variator belt.
Source [1]Spark plugs
Every 16,000 km
Replace the full set; worn plugs raise consumption and cause misfires.
Source [1]Air filter
Every 16,000 km
Replace more often in dusty conditions.
Source [1]Valve clearance
Every 16,000 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]Variator belt and rollers
Every 24,000 km
Replace the belt and check the rollers and clutch; a worn belt makes the scooter slip and can snap while riding.
Source [1]Coolant
Every 3 years
Replace the coolant and check the hoses and radiator; check the level cold between services.
