3D gel motorbike number plates have high-gloss black characters, each letter and digit cut from black vinyl and domed with a clear gel resin, on a 9" × 7" (approx. 230mm × 178mm) reflective yellow BS AU 145e plate, the size we make for motorcycles, quad bikes and scooters, with the registration set over two lines. It is sold as a single plate: a motorcycle carries a rear plate only, while a road-registered quad needs a front plate as well. Made in County Durham by a DVLA-registered number plate supplier. Order before 2pm on a working day with your documents approved and we make it the same day.
How it is made
The characters are black vinyl, cut in Charles Wright at the size and spacing prescribed for motorcycle number plates and applied to a reflective yellow plate carrying our supplier name, postcode and the BS AU 145e mark, and a clear polyurethane gel resin is applied over each character. The resin cures into a rounded, glass-like dome that keeps its gloss without fading. For square-edged raised characters see the 4D motorbike plate; for a flat plate see the printed motorbike plate. The car version is the 3D gel plate, and 3D gel versus 4D explains how the two constructions differ.
Is it road legal?
Yes, when the finished plate meets BS AU 145e and the number plate regulations, which allow a smaller character size on motorcycles registered from September 2001. Every 3D gel motorbike plate we make is built to them: Charles Wright characters, a single shade of non-reflective black, a reflective yellow background with no tint or pattern, and a registered supplier's mark. What stops a camera reading a plate is tint, a patterned background, a non-standard font or spacing, or damage, not the profile of the characters. Our guide to 3D and 4D number plate legality covers the rules, ANPR and infrared.
A proposed BSI amendment that would stop the production of raised-character plates was consulted on until 13 December 2025 and is still under consideration; nothing has been adopted, BS AU 145e:2018 remains the current standard, and 4D plates remain legal to make, sell and fit. We have not been told when any change would take effect or how plates already fitted would be treated, and we will say so here as soon as we are. Checked 8 September 2026.
Care
Motorbike plates can be washed with the bike. Gel characters can be pressure washed at a sensible distance and washed by hand; keep solvents and abrasive polish off them. See can I jet wash gel number plates.
Warranty
36 months against manufacturing defects, which covers the plate, the print, the gel and the bond between character and plate. It does not cover damage from fitting, impact or chemicals.
What to order
In the plate builder choose 3D gel and the motorbike size; for a motorcycle set the front plate to none, for a road-registered quad order a front plate as well. Proof of registration is required first (valid documents); postage is under delivery options. Use a screw kit through the bracket holes, or sticky pads on a flat bracket.
