Reg Plates Legality / Exhaust Heat Issue

Right, I just fitted a tail tidy kit (indicator unit not fitted in this photo) and the plate mounts really close the the big exhaust loop directly behind it.

This is a very American thing the way the plate mounts down there as I ordered this kit from America (Indicator unit & plate mount). My understanding is, they mostly use metal reg plates over there?

My only concern is when I got back and touched the plate, it was stupidly hot, to the point that I could wiggle the plate and it felt like jelly.

What is the actual law on plates (other than legal size), i.e. Do I have to have that yellow reflective surface on the back? Can I get a metal plate made up?

Hopefully this helps https://www.pepipoo.com/forums/lofiversion/index.php/t90123.html

It's for cars but I believe it is the same for motorcycles and pressed plates are not legal in the UK.

back the plate with metal?

Interesting read, seems that you can use metal plates as long as they meet them standards.

A guy a few posts down mentions there's specific rules for where to mount a plate as well, I wonder if mine is legal or not?

Going to all this effort only to have a 7x5 plate, which isn't legal anyway Laughing

But in saying that, I have been riding around for years with 7x5 plates and never been pulled up about it.

back it with some kind of heat proof material, I have had a similar issue on a pitbike, backed it with a bit of ally sheet and it was fine.

I found these: https://www.ebay.co.uk/itm/8-x-7-Motorbike-Motorcycle-Bike-Aluminium-Metal-PRESSED-Number-Plate-GIFTS-/291553566898?

He said he can do 7 x 5 with no black border

All seems legal but from what I understand of what i read it needs to be made from a reflective yellow, I don't know if metal pressed plates are going to be reflective as the plastic ones.

There's all sorts of stupidly detailed regulations about what reg. plates can be made of.

Including how much spring and deflection they have when supported on one end with a weight on the other.

Long story short. Metal can't possibly comply. It either premanantly bends too easily or is too stiff.

Nothing saying what you put behind your plate though. I'd suggest a piece of silicone matting.

So anyway I was sitting behind a Maibatsu CockThruster pickup today sporting a tiny plate completely devoid of BS AU 145d mark or maker's info, with a bold hexagon background and miniscule mostly hollow letters spelling out "L6 FKR" or similar and in conclusion you're massively over-thinking this.

Have to agree with Rogerborg. So long as your plate looks legal, who is really going to question it?

I don't think they care around here, had 7x5 and 9x3 in the last 5 years and never once got pulled up about them, even after a few run ins with the law over traffic offences.

Like already mentioned, as long as ANPR can ping you and it isn't ridiculously illegal (bad fonts, 3d, etc) I don't think they really care.

Been out again today and the plate has warped again with the heat. This metal one will be here next week so it will hold up until then (waste of £20 for the plastic one).

Why not do a vinyl sticker then stick that onto a bit of sheet metal. Job done.
