How to check a used motorcycle's MOT history before you buy

Summer is the peak season for used motorcycle listings. Private sellers and dealers know that buyers are motivated, the weather's good, and the urge to ride is strong. That's also why it's the easiest time to buy a dud if you're not careful.

The single best thing you can do before viewing any used bike — and it costs nothing — is pull its full MOT history. It takes about 30 seconds, and it can tell you more about a bike's real condition than an hour looking at it in a driveway.

How to run the check

Go to gov.uk/check-mot-history and enter the registration number. That's it. The service is free, official, and powered by DVSA data. You'll get the full MOT history going back to 2005 — every test the bike has ever had on record.

You can do this before you even contact the seller. There's no login, no account, no fee.

What the history shows you

For every MOT test on record, you'll see:

• The date of each test — pass or fail
• The mileage recorded at test time — this is crucial (more on this below)
• Any advisories — things the tester flagged as needing attention but not bad enough to fail
• Failure reasons — what exactly caused any failed tests

A clean list of annual passes with steadily increasing mileage and no repeat advisories is a good sign. What you're really looking for, though, is anything that breaks that pattern.

Red flag: mileage that goes backwards

Mileage clocking — winding back the odometer — is illegal in the UK, but it still happens. The MOT history is one of the best ways to catch it, because the mileage is recorded independently at each test.

If the mileage recorded in 2023 is lower than the mileage recorded in 2021, that's a serious problem. Walk away. The same applies to suspiciously flat mileage — a bike that records almost identical figures across several years might be one that's had its clock reset, or it may have been stored and not used, which brings its own issues.

A sudden mileage drop that coincides with a change of registered keeper is a particular red flag.

Red flag: the same advisory appearing repeatedly

An advisory means the tester noticed something that doesn't cause an immediate failure but should be dealt with. One advisory for worn brake pads is unremarkable. The same advisory for "slight play in head stock bearings" appearing across three consecutive MOTs is a sign the owner has been ignoring problems — or that the bike has a chronic fault that's never been properly fixed.

Look for patterns. Recurring advisories about chain and sprockets, oil leaks, or suspension components suggest a bike that's been run into the ground rather than maintained.

Red flag: gaps in the history

A motorcycle needs an MOT every year once it's three years old. If there's a two or three year gap in the history, the bike was either SORNed (declared off the road), used illegally, or the records weren't captured digitally. In any case, you need to understand what the bike was doing during that time.

A long period off the road can mean seized brakes, perished seals, degraded fuel, and corrosion in places that are hard to spot on a viewing. It's not automatically a dealbreaker, but it demands extra scrutiny.

Red flag: a string of failures

One failure, quickly retested and passed, is usually nothing. Multiple failures across different tests — especially for different reasons each time — suggests a bike that's been patched just enough to scrape through rather than properly maintained.

What the MOT history doesn't tell you

The MOT is a minimum safety standard, not a mechanical health check. A bike can pass its MOT and still have plenty wrong with it — worn consumables, tired suspension, a clutch that's on its way out. The MOT history is a starting point, not the full picture.

It also doesn't show finance outstanding on the vehicle, stolen status, or write-off history. For a full check on those, you'll need a paid HPI or vehicle data check from a service like the AA, RAC, or similar. For anything you're spending serious money on, it's worth the £15–20.

Use it every time, without exception

The check is free, it takes 30 seconds, and it has saved buyers from making expensive mistakes countless times. There is no good reason to skip it. Make it the first thing you do when a listing catches your eye — before you reply, before you call, before you drive an hour to view it.

If a seller objects to you checking the public MOT record on their vehicle, that's all the information you need.
