A Yamaha YFZ450R VIN is 17 characters. Positions 1–3 say who built it and where, 4–8 describe the body and engine, 9 is a check digit, 10 is the model year, 11 is the plant, and 12–17 are the serial number.

How to read a Yamaha YFZ450R VIN
Here is a real 2019 Yamaha YFZ450R VIN from our database, split into its parts:
VIN 5Y4AJ7134KA102635 — decoded free on its own report page.
| Position | Section | What it tells you |
|---|---|---|
| 1–3 | WMI | World Manufacturer Identifier — country, manufacturer and vehicle type. |
| 4–8 | VDS | Vehicle Descriptor Section — body style, engine, restraint system, series. |
| 9 | Check digit | A calculated digit that validates the whole VIN. Wrong digit = wrong VIN. |
| 10 | Model year | One character for the model year. Letters skip I, O, Q, U and Z. |
| 11 | Plant | The assembly plant that built the car. |
| 12–17 | Serial | Sequential production number of this exact vehicle. |
Where Yamaha YFZ450R VINs say the car was built
The first three characters are the World Manufacturer Identifier. Across 1 Yamaha YFZ450R VINs we have on file, these are the codes that actually show up — and the plants behind them:
| WMI | Built in | Vehicle type | VINs on file | Share |
|---|---|---|---|---|
| 5Y4 | United States | Motorcycle | 1 |
Country and vehicle type come from the NHTSA manufacturer registry. Share is measured across VINs decoded on ForCar, not production volume.
Model-year codes for the Yamaha YFZ450R
Position 10 carries the model year, skipping I, O, Q, U and Z. The alphabet comes round every 30 years, which the Yamaha YFZ450R has not yet outlived — its 16 years still map one-to-one. All 16 model years of the Yamaha YFZ450R, 2011 to 2026, with the character each one carries:
| Model year | VIN character (position 10) | Same character as |
|---|---|---|
| 2026 | T | — |
| 2025 | S | — |
| 2024 | R | — |
| 2023 | P | — |
| 2022 | N | — |
| 2021 | M | — |
| 2020 | L | — |
| 2019 | K | — |
| 2018 | J | — |
| 2017 | H | — |
| 2016 | G | — |
| 2015 | F | — |
| 2014 | E | — |
| 2013 | D | — |
| 2012 | C | — |
| 2011 | B | — |
When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.
Body and engine characters we see on Yamaha YFZ450R VINs
Positions 4 through 8 describe the build, and manufacturers assign them themselves — the same letter means different things on different marques. Across 1 VINs the Yamaha YFZ450R uses 3 different characters in these three slots alone — the ones below, ordered by how much of the Yamaha fleet each covers:
| Position | Characters seen on real VINs | Variety |
|---|---|---|
| 4 — body | A (100%) | 1 distinct |
| 5 — series | J (100%) | 1 distinct |
| 8 — engine | 3 (100%) | 1 distinct |
A character that dominates the column usually marks the body style the model was mostly sold in; a spread across several means multiple bodies or engines shared the same platform.

Where to find the VIN on a Yamaha YFZ450R
A Yamaha YFZ450R VIN normally opens with 5Y4. Four places on the car carry the full number, and all four must agree — on a Yamaha YFZ450R, a plate that disagrees is where fraud shows itself first.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tyre pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions
Is this Yamaha YFZ450R VIN decoder free?
Yes — decoding a Yamaha YFZ450R VIN costs nothing and needs no account. You get the year, plant, body and engine characters, plus recalls and owner complaints filed with NHTSA.
How many characters is a Yamaha YFZ450R VIN?
Seventeen, on every Yamaha YFZ450R built from 1981 onwards, when the 17-character format became mandatory in the US. The oldest Yamaha YFZ450R VIN on file here is a 2019, so everything in our Yamaha data already uses the modern layout.
Why do two Yamaha YFZ450R model years share the same VIN character?
Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. A 1995 and a 2025 car can carry the same letter. The check digit and serial range separate them.
Can a Yamaha YFZ450R VIN tell me if the car was in an accident?
Not from the characters themselves — they describe how the Yamaha YFZ450R left the factory, not what happened to it afterwards. Crash and title records sit in separate databases keyed to the same number. Run the number through our VIN check to see what is on the record for it.
Do the body and engine characters mean the same thing on every Yamaha?
No, and that is the usual mistake — positions 4–8 are assigned per model, not per brand. A letter that means one body on the Yamaha YFZ450R can mean a different one on another Yamaha, and something else again on another marque. On Yamaha YFZ450R VINs the character that dominates position 4 is A — read it against the table above, not against a generic chart.
What if the VIN on the dashboard doesn't match the door jamb?
Treat it as a red flag on any car, and on a Yamaha YFZ450R check the prefix first: a genuine one opens with 5Y4, and a plate that starts otherwise did not come off this car. Beyond that, mismatched plates mean either a replaced panel or a tampered identity — ask for documents and verify before any money changes hands.
