Certificate of conformity for a motorcycle or scooter
Imported motorcycle, scooter, moped or quadricycle: category L, its certificate of conformity, where to find the frame number and what to watch out for when buying. Motorcycles, scooters, mopeds, tricycles and quadricycles form category L and have European type approval.

Category L, from moped to quadricycle
European type-approval law places light two-, three- and four-wheeled vehicles in category L. It covers a very wide range: mopeds, scooters, motorcycles of every capacity, powered tricycles and light and heavy quadricycles.
As for cars, these vehicles are type-approved at European level, and the certificate of conformity issued by the manufacturer certifies that the individual machine corresponds to an approved type. That is the document required to register a two-wheeler bought in another Member State.

Where to find the identification number
On a two-wheeler there is no windscreen and no door pillar: the number is stamped directly into the frame. The most common locations:
- on the steering head, at the front of the frame, below the handlebars;
- on the frame tube on the right-hand side, sometimes hidden by fairing;
- on a manufacturer’s label under the seat or inside a scooter’s storage compartment;
- copied onto the registration document of the country of origin.
The engine number, stamped on the casing, is a different identifier: it does not identify the type-approval file. Do not confuse the two.
Three things to watch on two-wheelers
- Restricted versions. The same motorcycle can exist in full-power and restricted form depending on the market. The certificate describes the approved version, and that is what counts.
- Modifications. Exhaust, air filter, final drive: two-wheelers are modified more often than cars. None of it appears on the certificate, which describes the machine as it left the factory.
- Imports outside the network. A motorcycle sold new in Japan or the United States has no European certificate. On sought-after older machines the case is far from rare: the frame number settles it.
Why category L is a case apart
On a car, variation comes mainly from options and trim. On a two-wheeler it comes from power and licence. The same machine may be sold at several power levels depending on the market, each corresponding to a distinct approval, and the licence required depends on that level. The certificate of conformity is what establishes, unambiguously, which version you have.
A second factor is service life. Motorcycles cover few kilometres a year and stay in use far longer than cars. Machines of fifteen or twenty years in excellent condition are common. Yet the ten-year rule applies to category L too: beyond it, issuing a duplicate is no longer an obligation for the manufacturer. In practice this is the leading cause of a blocked two-wheeler file.
A third, happier factor: motorcycle manufacturers often keep remarkably complete records by frame number, including for older models. A negative answer on a twenty-year-old car is close to certain; on a motorcycle of the same age it is worth trying.
Prices and scope
Our public price list covers car manufacturers. Two-wheeler brands are not in it: they are handled case by case, and the exact price and turnaround are confirmed before anything is started.
A few manufacturers in our list also build two-wheelers or quadricycles: in that case the request channel is the group’s.
