Do you need a new or replacement number plate for your ride? Here’s everything you need to know.
What size are motorbike number plates?
Demon Plates supplies the standard size of bike registration plates, which is 228mm x 178mm (9”x7”).
While there are no precise rules on a plate’s dimensions, the characters it contains must meet specific requirements.
What is the legal requirement for a motorcycle number plate?
As a registered number plate supplier (RNPS), we use a prescribed font, and arrange the letters and numbers in a way that complies with the law. According to rules set by the Driving Licence and Vehicle Authority (DVLA), the characters on a number plate need to be a certain height and size.
For bike number plates, that includes:
- They must be 64mm tall
- All characters (except the number 1 or letter I) must be 44mm wide
- The character stroke (the thickness of the black print) must be 10mm
- The space between characters must be 10mm
- The margins at the top, bottom, and side must be at least 11mm
Like cars, custom motorcycle plates must comply with the latest British Standard number (BS AU 145d until September 2021), which includes a rear plate made of reflective material comprising black characters on a yellow background.
For more information, see DVLA leaflet INF104.
Where should you display a bike number plate?
Motorcycles registered on or after September 1, 2001, must only display a number plate at the rear.
If yours precedes that date, then you can also display a number plate at the front, but do not have to.
Are bike number plates legal on cars?
No, they are not.
Because of their different sizes, and the associated rules that prescribe the required character size and spacing, the rules – as described above – are not the same for car and motorbike registration plates in the UK. That means you cannot display bike plates on a car.
Can I have black bike plates?
Vehicles made before January 1, 1973, may display traditional ‘black and white’ number plates (for example, white, silver, or grey characters on a black plate).
Meanwhile, from April 2020, vehicles manufactured before January 1, 1980, can also display traditional ‘black and white’ number plates.
To do so, you must:
- Apply to DVLA
- Be within the ‘historic vehicles’ tax class
If you see a modern bike with a black and white number plate, it’s probably not road legal.
Can I put a private plate on my motorbike?
Yes, of course you can.
The rules for transferring a private registration number between vehicles, whether it is a car or motorcycle, are the same.
The DVLA will charge you a number plate transfer fee, determined by whether the number you want to transfer is already on an existing vehicle, is on retention, or on a Certificate of Entitlement.
If it is the former, you must apply to the DVLA using a V317 form.
