> What to check before buying a used motorbike: frame and engine numbers, stolen and write-off records, MOT history, and what to inspect in person.

Motorbikes are easy to steal, easy to disguise and often repaired after a crash, so a used bike deserves more checking than its price suggests. Here is what to check before you buy.

## 1. Run a motorbike check by registration

Our free [motorbike history check](https://carcheckup.co.uk/bike-history-check) works as a motorcycle reg check: it shows the DVLA details, tax and MOT status, and the full MOT history. The full report adds outstanding finance, insurance write-offs and police stolen markers.

## 2. Match the frame and engine numbers

Every bike has a frame number (the VIN, usually stamped on the headstock) and an engine number. Both should match the V5C logbook. Filed, re-stamped or painted-over numbers are a serious warning sign. See where to find the [engine number](https://carcheckup.co.uk/engine-number-check) and the [VIN](https://carcheckup.co.uk/vin-check).

## 3. Check for theft and write-off records

A [stolen check](https://carcheckup.co.uk/stolen-car-check) applies to motorbikes too. Write-off categories (Cat S, N, C and D) work the same way as for cars: a Cat S or N bike can be repaired and ridden, but it should be cheaper and properly repaired.

## 4. Read the MOT history

Motorbikes need an MOT from three years old. The [MOT history](https://carcheckup.co.uk/mot-check) shows the mileage at each test and advisories such as worn tyres, brakes or chain and sprockets, which tell you what may need doing soon.

## 5. Inspect the bike in person

- Scuffed bar ends, levers, footpegs and fairings: signs the bike has been dropped.
- Chain and sprockets, tyres and brake discs, which are costly to replace together.
- Fork seals for oil leaks, and the steering for notchiness.
- A cold start: ask the seller not to warm the bike up before you arrive.

## 6. Check the paperwork and pay safely

Ask for the V5C, service records and both keys. Be wary of a bike offered without its logbook. See [how to pay safely](https://carcheckup.co.uk/blog/how-to-pay-safely-for-a-used-car-in-the-uk/) and [common scams](https://carcheckup.co.uk/blog/common-used-car-scams-in-the-uk-and-how-to-avoid-them/).
