UK MOT test regulations on ABS v's brake upgrades

[nurse]

My 92 FJ ABS is currently in having the blue dot upgrade done (amoungst some other bits and pieces).  I popped in to check on progress and the mechanic said there was a bit of a problem!  Ok, I said, what is it? Thinking there was some major mechanical malfunction with the calipers and master cylinder i had provided

New MOT regs here in the UK (he did tell me from when but i forget the date he said) state that any bike fitted with ABS can no longer have it disabled or removed!!  As he knows the bike well and acknowledges that the new brakes will be way better and therefore safer than the original ABS was anyway, he is happy to plead ignorance and pass it during its annual MOT test.  But did say that he shouldnt and if i take it elsewhere in the future, strictly speaking they will most likly fail it.

I did highlight that ABS was optional until about my year of manufacturer so unless an anorak (like most of us on here) how would they know whether it had it or not!! Not widthstanding the large ABS decals on the side of course, but as we know they dont mean anything, they can be removed, painted over or the panels transplanted between similar but not identicle bikes!!

Anyone else come across this issue?  I appreciate this is going to be a bit of a uk focused question but any thoughts/advice welcome.  Any other brits found this problem and therefore a way round it?

If that's correct, that could be scary for quite a few BMW 1150GS riders with servo assisted brakes, who have removed the servo after it failed.
