About 4D Motorcycle Number Plates

4D-style motorcycle plates use raised characters to give a sharper, more dimensional appearance. The look can work well on a modern road bike when the precise construction complies with current UK rules.

Demon Plates lets you start with the intended registration or plate text and review the finish before ordering. Decide first whether the plate is for public-road use or a private display.

What Size Are 4D Motorcycle Number Plates?

Motorcycles registered from 1 September 2001 must display a rear plate, with the prescribed two-line character layout. The familiar 9 by 7 inch motorcycle product format is common, but legal compliance depends on the characters, margins and registration, not a single universal outer size.Where the plate is intended for a UK public-road vehicle, the prescribed character layout, font, spacing, margins and supplier markings matter as well as the outer plate dimensions.

Replacement 4D Motorcycle Number Plates

Replacing a broken or fading rear motorcycle plate keeps the registration readable in wet and dirty conditions. Measure your existing holder and check that the new plate does not interfere with lights or reflectors.

Check the existing mounting area, registration details and intended use rather than choosing solely by appearance.

Choosing and Fitting 4D Motorcycle Number Plates

Choosing and Fitting 4D Motorcycle Number Plates


Secure a motorcycle plate so it stays upright and clearly visible from behind. Check existing fixings, plate bracket clearance and any vibration-resistant mounting arrangement.

Keep all characters unobstructed. Where there are cameras, lamps, sensors or specialised mounting parts nearby, follow the vehicle manufacturer’s advice.

Are 4D Motorcycle Number Plates Legal?

UK road-use number plates require the correct reflective colours, character format and supplier markings. For plates made or fitted after 1 September 2021, BS AU 145e applies.

A compliant raised-character style may be permitted, but novelty graphics, improper flags, manufacturer badges and altered characters do not become legal simply because a plate is custom-made.

4D Motorcycle Plates and UK Law

The rear plate needs the correct spacing, font, reflective background and manufacturing marks. The raised effect itself is not a blanket exemption from other number plate rules.

If in doubt, measure your vehicle and check the official number plate guidance before confirming your order.
