Understanding German Motorcycle Registration Papers: Hidden Clues

You're standing in front of the motorcycle you want. The paint shines, the silencer sounds good, and the seller says: "Well looked after, German model, accident-free." Before you sign the contract and hand over a few thousand euros, there's a step many underestimate or simply forget: understanding the registration papers and checking them carefully. This guide is about German papers, which matters if you buy a used motorcycle in Germany.

The registration certificate Part I and Part II (Zulassungsbescheinigung Teil I and Teil II, formerly Fahrzeugschein and Fahrzeugbrief) is more than a form for the authorities. It tells the motorcycle's story. If you can read it, you'll quickly see whether the machine was once restricted, whether it was imported from overseas by a roundabout route or whether it has modifications that will cause trouble at the next roadworthiness test (TÜV).

Here you'll get the fields and codes explained that registration offices and inspectors usually work with. That way you can check for yourself when buying used, instead of relying on the seller's word.

Registration certificate Part I and Part II: the basics

The EU-harmonised documents have existed in Germany since 1 October 2005. They were meant as a simplification. For laypeople, though, they've become rather more confusing, because much of the information now sits in numbered, coded fields that mean little without explanation.

Registration certificate Part I (Fahrzeugschein)

You must carry this document on every ride. It contains the technical data that count for the police at a check. Important for you: this is where the currently valid performance data are, and field 22 contains all special entries.

Registration certificate Part II (Fahrzeugbrief)

The Part II is best kept safe at home (or at the bank if the motorcycle is financed). It identifies you as the keeper. Important for you: here you see the number of previous owners and, crucially, where the vehicle comes from. If the document was only issued as a replacement two weeks ago, you should ask more questions.

How do you recognise a replacement document?

Look at the official notes in the registration certificate Part II. A replacement document usually carries a note that it was issued as a replacement, for example because of loss.

Type code "0000": spotting a grey import

For used buyers, this is probably the most important point. A grey import is a motorcycle that didn't come into the country through the official German distribution (such as BMW Motorrad Deutschland or Honda Deutschland) but through independent importers from markets such as the USA, Japan or the Emirates.

Finding the type code (TSN)

Look at field 2.2 in the registration certificate Part I. On a regular German model you'll find a combination of three letters or numbers there, for example "AAV". This tells parts dealers and insurers exactly which model it is.

If there are only zeros (0000 0000), the vehicle has an individual approval (Einzelbetriebserlaubnis) under § 21 StVZO.

Why "0000" can be a problem (but doesn't have to be)

Many buyers only see the low price and don't know what a zeroed type code means in everyday life:

1. Insurance: because the system doesn't recognise the model automatically, you're often classified manually, usually in a more expensive class.

2. Spare parts: if you want to order brake pads online, searching by type code won't help. Every time, you have to check yourself whether parts for the EU model really fit.

3. Technical differences: a Yamaha R1 from the USA may have different headlights (without E-mark), different emissions control or even a different software map than the German model.

4. Resale value: among collectors and on the normal used market, "genuine German models" fetch noticeably more money (with Harley-Davidson the VIN gives a first clue, but only the manufacturer can confirm). An import almost always trades at a discount. On carfax.eu you can check the history of individual motorcycles.

Checking for restrictors: power isn't always power

A lot of trickery goes on, especially with A2 beginner motorcycles. You should know two cases.

Case A: secretly derestricted

The papers say 35 kW (48 hp), but the motorcycle pulls much harder. The seller grins: "It's open, has about 100 hp, but it's registered as A2. Saves on insurance." That's exactly the trap.

• Legally: the operating permit has lapsed. In an accident, your insurance cover is gone.

• Criminally: if you only have an A2 licence, you're riding without a licence.

Case B: the restricted 100 hp machine

An EU rule has applied since 2013: in its unrestricted state, an A2 motorcycle may produce at most 70 kW (95 hp). If you buy an older motorcycle that has 120 hp unrestricted and is restricted to 48 hp, you may not legally ride it with today's A2 licence in many EU countries. That applies even if the restrictor is properly registered.

How to read the power history in field 22

Field 22 is the free-text field at the end of registration certificate Part I. Every change ends up here. Look out for wording such as:

• "Leistungsreduzierung durch Gaswegbegrenzer, H=24mm" (power reduction by throttle stop)

• "Leistungssteigerung durch Ausbau der Drosselblenden im Ansaugtrakt" (power increase by removing the intake restrictors)

If a power increase is entered, look at the date. Was the motorcycle ridden restricted for the first 30,000 km? That can affect engine wear, for example through carbon deposits on the valves if the engine was never really "blown out".

Country code in the VIN: where does the motorcycle really come from?

Besides the type code, there's a second feature that reveals a lot: the vehicle identification number (VIN). You'll find it in field E.

The first three characters (the world manufacturer identifier) show you where the motorcycle was built. The first character stands for the region:

• J: Japan (e.g. JH2 Honda, JYA Yamaha, JS1 Suzuki, JKA Kawasaki)

• Z: Italy (e.g. ZDM Ducati)

• V: France or Spain

• 1, 4, 5: USA (e.g. 1HD, 5HD Harley-Davidson)

• W: Germany (e.g. WB1 BMW)

Harley-Davidson special case: the first characters of the VIN (such as 1HD or 5HD) give a clue to the target market. But that alone isn't reliable. Only an enquiry with the dealer or manufacturer gives you certainty. Some US machines come to Germany via Lithuania or Poland, often with a "salvage title" (i.e. a write-off in the USA) and cheaply repaired. A look at the VIN in field E can therefore show you whether you're looking at a US accident motorcycle.

Fields 17 and 18: approval status

These small fields are easy to overlook. But they're crucial for legality.

• Field 17 (type of operating permit): here you see on what basis the motorcycle is registered: EU type approval (European standard, can be registered in any EU country without problems), national type approval (usually older vehicles or small series) or individual approval (typical for imports or heavily modified custom bikes).

• Field 18 (vehicle length): there are often discrepancies here if the rear has been shortened. If the motorcycle looks much shorter than field 18 states and the original value is still there, the modification wasn't registered.

Field 22 in Part I: what it really says

Field 22 lists all deviations from standard condition. These entries affect the value:

1. Tyre brand binding

This used to often say: "Reifenbindung gemäß Betriebserlaubnis beachten" (observe tyre binding according to operating permit). Note: for motorcycles with EU type approval there's no longer any brand binding, but other sizes still need an inspection (more on this in our tyre guide). If tyre brands that no longer exist are entered here, budget for new tyres and a TÜV inspection (approx. €100).

2. Replacement frame

Does it say something like "Austauschrahmen Nummer..." (replacement frame number)? That's a clear warning sign. A frame is only replaced if the old one was unusable because of an accident or rust. So the motorcycle had serious damage. That lowers the value considerably, even if the repair was done professionally.

3. Special handlebars and accessories

Every modification (LSL handlebars, Akrapovic exhaust without E-number, rearsets) must appear here. If the parts are fitted but not registered, ask for the ABE (general operating permit) on paper. Without it, there'll be trouble at the next check.

Previous owners: the "disappearing" keepers

The registration certificate Part II shows the number of previous owners. A popular trick: if a motorcycle has passed through many hands (e.g. 6 previous owners), it looks bad on paper. Some sellers then briefly deregister the motorcycle and apply for a new Part II because of "loss" or "damage". The new document shows a 1 for the keeper again (the current keeper), but underneath in small print: "number of previous owners according to old document: 5".

So read this small print below the keeper field carefully. If it says the document was reissued because of loss, ask for the old one or a copy. Anyone with nothing to hide keeps copies of the old documents.

Compare first registration and year of manufacture

A motorcycle can be "newly" registered and still be three years old.

• Field B: date of first registration.

• Field (6): date relating to K, i.e. the date the type approval was granted.

Some machines sit at the dealer for years as shelf warmers. Technically that's usually OK, but rubber ages. Look at the DOT number on the tyres (four digits, e.g. 1222 = week 12 of 2022). If the motorcycle was first registered in 2025 but the tyres are from 2021, it stood around for four years. That can lead to flat spots and hardened seals.

Price negotiation: using flaws in the papers

If you've found inconsistencies (e.g. an import with "0000" or a concealed restrictor), you have a clear advantage in price negotiations.

How to proceed:

1. Don't complain straight away: let the seller talk first. If they say "German model" and you see "0000", you know their statement isn't true.

2. Put a figure on the costs: "Look, this is a US import. For the next TÜV I might need confirmation for the lighting, and spare parts are harder to find. On the market it's worth at least 800 euros less."

3. Draw a clear line: "A motorcycle with a replacement frame is an accident vehicle for me. I'll only buy it with a significant discount of 20%."

Checklist: check the papers in 5 points

Before you count out the money, go through these five points:

1. Field 2.2: does it say "0000"? If so: check the import and negotiate the price.

2. Field E (VIN): does the number on the frame match the papers exactly? Are there scratches around the stamped number?

3. Field 22: are restrictors or modifications entered that can no longer be seen on the motorcycle? Or vice versa?

4. Previous owners: does the number of keepers fit the condition and what the seller tells you?

5. TÜV reports: do the mileages rise logically over the years?

In a nutshell

Buying a motorcycle is emotional; looking at the papers shouldn't be. If you understand the hidden clues in the registration papers, you protect yourself from botched work, expensive import traps and legal problems. An honest motorcycle has a traceable paper history. If the seller gets nervous when you ask about the documents, put your helmet back on and keep looking.
