Motorcycle VIN decoder
Every road-legal motorcycle sold in the US since 1981 has a 17-character VIN, just like a car. It tells you who built the bike, the model, the engine, the model year and the factory, and it’s the key to checking recalls before you buy.
Enter any motorcycle VIN below. It works for Honda, Yamaha, Kawasaki, Suzuki, Harley-Davidson, Indian, BMW, Ducati, Triumph, KTM and any other maker that reports to NHTSA.

Motorcycle manufacturer codes (WMI)
The first three characters of the VIN are the World Manufacturer Identifier. These are the ones you’re most likely to see on vehicles sold in the United States:
| VIN starts with | Meaning |
|---|---|
JH2 | Honda motorcycles |
JYA | Yamaha motorcycles |
JS1 | Suzuki motorcycles |
1HD | Harley-Davidson |
56K | Indian Motorcycle |
WB1 | BMW motorcycles |
ZDM | Ducati |
SMT | Triumph |
VBK | KTM |
Not sure what the rest of the characters mean? Our guide to what each digit in a VIN means walks through all 17, and the VIN year chart shows how to read the model year from the 10th character.
How to read a motorcycle VIN
The first three characters name the maker
Japanese brands start with J, like JH2 for Honda and JYA for Yamaha. Harley-Davidson uses 1HD, Indian uses 56K, BMW motorcycles use WB1, Ducati ZDM, Triumph SMT and KTM VBK. If the code doesn’t match the brand on the tank, ask questions.
Model year is the 10th character
Motorcycles use the same year codes as cars, but the 7th-character rule that separates 1990s from 2020s doesn’t apply to them. Use the decoded year, or common sense, to tell the cycles apart. Our VIN year chart lists every code.
Expect fewer details than a car
Motorcycle makers report less to NHTSA than carmakers do. You’ll usually get the make, model, year, engine size and plant. That’s still enough to confirm the bike matches the ad and to check for recalls.
Before you buy a used motorcycle: what to check with the VIN
Once you’ve decoded the VIN, these are the motorcycle-specific things worth comparing against the listing.
Check the VIN on the frame, not just the paperwork
Stolen bikes sometimes come with altered paperwork. Make sure the frame stamp matches the title exactly, and that it doesn’t look ground down or restamped.
Confirm the model and engine size
Many bikes come in several engine sizes that look similar. The decoded engine row settles it.
Ask about recalls and service
Recalls are free at a dealer. Ask for receipts for any recall work and for regular services like chain and valve checks.
Where to find the VIN on a motorcycle
Look at the steering neck, the part of the frame the handlebars turn on. The VIN is usually stamped there or printed on a sticker on one side. Some bikes also have it on a frame rail near the engine. The engine has its own number, which isn’t always the same as the VIN. See all the places to look.
