How to Find a VIN on a Motorcycle, ATV, or Dirt Bike (With Free History Checks)
Thinking of buying a used motorcycle, ATV, or dirt bike? Before you hand over any cash, one of the most important things you should do is locate and verify the Vehicle Identification Number (VIN).
The VIN is a 17-character code that acts like a fingerprint for the vehicle. It reveals where the bike was made, who built it, whether it has been stolen, wrecked, salvaged, or had its mileage altered. Skipping this step is one of the most common — and expensive — mistakes buyers make.
This guide will show you exactly where to find the VIN on motorcycles, ATVs, and dirt bikes, how to confirm it’s real, and how to run a free VIN check using VinCheckPro before you buy.
What Is a VIN and Why It Matters
A VIN (Vehicle Identification Number) is a standardized 17-character code used on all motor vehicles built since 1981. It contains key information about the vehicle, including:
- Manufacturer and country of origin
- Model, engine, and trim
- Model year and plant of assembly
- Title and registration identity

that number is checked against government and industry databases to reveal:
- Theft records
- Salvage or rebuilt titles
- Accident and insurance claims
- Odometer rollbacks
- Open recalls
It’s your first line of defense against fraud.
Where to Find the VIN on a Motorcycle
Most motorcycles have the VIN stamped on the frame, not the engine.
Look in these places:
- Stamped directly into the metal or printed on a metal plate or sticker
Turn the handlebars fully to the left and shine a flashlight at the side of the frame where the fork meets the body.
Important:The engine number is NOT the VIN. Always use the number stamped on the frame.
Where to Find the VIN on an ATV (Four-Wheeler)
ATV VINs are stamped into the chassis, not removable parts.
Check these common locations:
If you don’t see it right away, clean the frame — mud, rust, or skid plates often hide it.
Where to Find the VIN on a Dirt Bike
Dirt bikes follow the same layout as street motorcycles.
Look for the VIN:
Move cables or plastic slightly if they block your view.
How to Know You Found the Real VIN
Not every number stamped on a bike is a VIN. Use this checklist:
| Feature | Real VIN | Not a VIN |
|---|---|---|
| Length | 17 characters | Usually shorter |
| Location | On the frame | On engine, swingarm, or parts |
| Characters | Letters & numbers (no I, O, Q) | May include odd characters |
| Label | “VIN” or “Frame No.” | Often unlabeled or “Engine No.” |
If the number isn’t 17 characters or isn’t on the frame, it’s not the VIN.
If the VIN Is Hard to Read
Try these tricks:
- Shine a flashlight at a low angle
- Clean with a cloth and degreaser
- Rub chalk or pencil over the stamp
- Remove plastic covers or guards
- Look for a secondary VIN sticker
A faint or damaged VIN can still be legitimate — but heavy grinding, welding, or mismatched plates are serious red flags.
