Step by step
- 1
Check the steering neck
The frame VIN is most often stamped on the steering neck (headstock), below the handlebars.

Look at the engine case
The engine has its own number; note it, but the frame VIN is the one used for titling and history.
- 3
Confirm against the title
Match the frame VIN to the title and registration. A mismatch is a serious warning.
- 4

Are motorcycle VINs 17 characters?
Yes, for modern bikes. Some older motorcycles used shorter, non-standard numbers, similar to pre-1981 cars.
Is the engine number the VIN?
No. The engine number is separate. The frame VIN — usually on the steering neck — is the identifier used for titles and history reports.
