A motorbike with no plate is not allowed on a public road: in Great Britain a motorcycle must display a registration plate at the rear, and riding without one, or with one that is missing, illegible or non-standard, is an offence that the police can act on. Unlike a car, a motorcycle needs a rear number plate only, with no front plate required, and the plate is made smaller to suit the machine. The Driver and Vehicle Licensing Agency (DVLA) records the registration and the rules sit with the Department for Transport.
Part of Personalised Number Plates. Start with the main guide: Cherished Plates: What They Are and How They Work
Updated October 2026 · Independent information, not legal advice
Plates on bikes are shaken loose by vibration, hidden by tail tidies and bought from the wrong source, so the practical questions matter as much as the law. This explains what a bike must show, how the size and layout differ from a car plate, what happens if a plate is missing, and how to replace or personalise one without breaking the rules.
What Are The Rules For Motorcycle Number Plates?
Motorcycle number plates must be displayed at the back of the machine, in the right colour, in the right typeface and made by a registered supplier. The rules are set out on GOV.UK and apply to anything registered as a motorcycle in Great Britain.
Does a motorbike need a front plate?
No. A motorbike needs a rear plate only. A front plate is not required, and the plate fitted at the rear must be clearly visible to following traffic and cameras.

A motorbike reg plate has a yellow reflective background with black characters, the same colour as a car's rear plate. A white front plate is not part of the requirement.
Is a plate needed for every motorbike?
Almost every road-registered motorcycle needs a plate. Some historic or specially exempt machines may follow different rules, so check GOV.UK for your vehicle type.
What Does A Bike Number Plate Look Like?
A bike number plate is usually a compact, two-line plate, with the characters stacked in rows so they fit the available space, using a smaller character size than on a car.
Why is the layout in two lines?
Space at the rear of a motorcycle is limited, so the standard allows a layout that fits the machine. The characters still have to follow the legal font and spacing.
What typeface does the plate use?
The same legal font as other plates, a version of Charles Wright 2001. See car registration plate font for the shapes.
What Size Is A Motorcycle Number Plate?
Motorcycle number plate size is smaller than a car's. The characters are shorter and the whole plate is more compact, and the exact dimensions are in the standard and on GOV.UK.

Frequently Asked Questions
Do motorbikes need a number plate?
Yes. A road-registered motorbike must display a registration plate at the rear. It does not need a front plate. The plate must be yellow with black characters, made by a registered supplier to the British Standard, and kept clean and legible. Check GOV.UK for the exact rules for your vehicle type.
What size is a motorcycle number plate?
A motorcycle plate is smaller than a car plate, with shorter characters and often a two-line layout to fit the limited space. The exact dimensions are set by the British Standard and are on GOV.UK. A plate trimmed or shrunk below the standard is not legal on the road.
What is the smallest legal motorbike number plate?
The smallest legal plate is the reduced size the standard allows for motorcycles, with characters of the required height, width and spacing. It is not a matter of choice. A custom micro plate that departs from the standard is not legal, however tidy it looks.
Is a motorbike with no plate illegal?
Yes. Riding a motorbike on a public road without a legal rear plate is an offence. You could be fined, and the police can stop and check the machine. If a plate is lost, replace it from a registered supplier before riding again.
What colour is a motorbike number plate?
The rear plate is yellow with black characters, the same as a car's rear plate. A front plate is not required on a motorcycle, but if a keeper chooses to fit one it should still be compliant. The plate must also be reflective and carry the supplier's details.
Can I buy a motorbike plate online?
Yes, from a registered number plate supplier. The supplier must see proof of your identity and entitlement to the registration number, such as the V5C. A seller who does not ask for documents is not following the rules, so choose another supplier.
Can I put a private plate on a motorbike?
Yes, if the motorcycle meets the DVLA's conditions. A private plate can be assigned to a bike in the same way as to a car, using the DVLA's online routes or the V317 form route. The number must not make the bike look newer than it is, and the DVLA issues a new V5C.
Will a damaged number plate fail an MOT?
It can. The condition, security and legibility of the registration plate form part of the MOT test on a motorcycle in Great Britain, so a cracked, faded or loose plate may be recorded as a defect. Replace it before the test to avoid a failure.
Are tail tidies legal?
A tail tidy is acceptable only if the plate remains clearly visible, correctly positioned, readable and properly lit. If it hides, angles or shrinks the plate so it cannot be read, it can lead to an offence and an MOT defect. Check the legal position on GOV.UK before fitting one.
Can I make my own motorbike number plate?
No. Only a registered number plate supplier may make plates for road use. Home-made, printed or sticker plates are not legal, and altering a plate with paint or stickers is not allowed. Order a compliant plate and provide the supplier with the documents it needs.
Do Northern Ireland motorbikes need plates too?
Yes, motorcycles in Northern Ireland also display a rear plate. Registration and vehicle tax are handled by the DVLA, while vehicle testing is run by the Driver and Vehicle Agency (DVA). The plate format is different from Great Britain, so check the official guidance for the details.
How do I check a motorbike by its registration?
Enter the registration into a free number plate check to see its make, model, colour, year, MOT history and tax status. The check does not show finance, write-off or stolen data, or owner details, so for a purchase consider a full history check and compare the frame number with the V5C.
