I found this website that seems to supply aftermarket replica road bodywork kits for £286 = 103 PNP ... you'd need to add import tax, which I think will work out to about £60 so about £450.
There's a kit on sale on e-bay from somebody who bought and didn't use it for a bit more.

They cover the 250's, 3en2, and 3TJ. The also seem to offer a special paint service which could be useful, have a look at the other bikes for a few ideas

If you do get or have one then let us know how it goes

Had a look at it mate,very tempted for the 3tj. I have seen an article in I think Practical Spotsbike mag giving it the thumbs up a couple of years ago.

I reckon as long as long as you take your time fitting it and don't expect to much you'll be pleasantly surprised
