Buying a Used Scooter: A Checklist That Finds the Expensive Problems

A used scooter is often the right buy. It is also the easiest vehicle in the world to sell with a hidden problem, because the parts that fail expensively are the parts a buyer cannot see. Work through this in order: paperwork first, because no amount of mechanical condition fixes a title problem.

Paperwork, before anything else

Does the seller's name match the title? If it does not, walk away. "Selling it for my brother" is how stolen and lien-encumbered vehicles get moved.

Does the VIN on the frame match the title? Find the stamped VIN, not just the sticker, and read it character by character. For anything with a full 17-character VIN you can decode it free through NHTSA's VIN decoder, which will confirm the make, model year and vehicle type match what you are being told. The National Insurance Crime Bureau's VINCheck will tell you free whether a VIN has been reported stolen or written off by a participating insurer.

Is it titled as what you think it is? A machine titled as a motorcycle needs motorcycle licensing even if the seller calls it a moped, and a machine that was never titled at all can be difficult or impossible to register in some states. Our class checker covers what to confirm.

The cold start

Insist on seeing it started from cold, and arrange the viewing so that is possible. A warmed-up engine hides hard starting, and a warmed-up battery hides sag. If you arrive and it is already running, come back another day.

Petrol scooter: what to look at

Starting. Should catch within a few seconds on the starter. Extended cranking, or needing the kick start, points at carburettor or fuel system work.
Smoke. Blue smoke is oil, and on a four-stroke that is expensive. A little at first start on a two-stroke is normal.
The CVT. Ride it. Acceleration should be smooth and continuous. Juddering, slipping or a whine that rises without the scooter accelerating means belt, rollers or clutch work.
Oil. Check the level and the colour. Milky means water.
Chassis. Look under the plastics at the frame near the steering head and the engine mounts for repairs and rust.

Electric scooter: what to look at

Ask for the odometer reading and the charge cycle count if the display offers it. Cycle count is the honest measure of pack age.
Test range, not just voltage. A pack can read full and collapse under load. Ride it hard for a few minutes and watch whether the gauge falls in steps.
Check for swelling and smell around the battery compartment. Any of either, walk away, and do not let the seller charge it in your presence to prove otherwise.
Water ingress. Corrosion on connectors and green tarnish on contacts means it has been ridden or stored wet, and electrical faults will follow.
Is the pack still available? On a discontinued budget model the answer is often no, and that caps the machine's remaining life regardless of condition.

Both: the mechanical five

Tyres. Date code and tread. Old rubber hardens and grips poorly even with tread left.
Brakes. Pad thickness, disc scoring, lever feel.
Suspension. Push down hard on the front. It should return once, not bounce. Look for fork oil on the sliders.
Steering head. Front brake on, rock the scooter forward and back. A knock is head bearings.
Wheel bearings. Spin each wheel off the ground and listen for rumble.

Price it against what it needs

Total up the deferred maintenance you found and subtract it. Tyres, a belt, a service and a battery is not a bargain at a bargain price. On electrics, a pack replacement alone can exceed what the whole scooter is worth.

If in doubt, pay a shop

An hour of a mechanic's time is the cheapest insurance available on a four-figure purchase, and a shop that does not know the seller will tell you the truth. Find a scooter service shop near where the machine is and ask whether they do pre-purchase inspections. Most do.
