Not bad, but the price is a little bit higher than I'd like to spend, I don't think they'd be too difficult to make, either.
I've found an Italian company that make a set for the BMW:

They're aluminium and shiny zinc plated, I think the style suits the BMW as well, 186 euros isn't too much, either.
I don't think the airhead looks right with rearsets that look as though they were designed for an R1!
The bike I'm building will have an R75/5 TLS front drum bake, drum rear, spoked wheels, short stainless front mudguard, no visible switchgear and shortened silencers. I'm trying to keep it really simple and clean-lined.
I'm also building a second one with powder-coated alloy wheels, (drum rear), standard switchgear, silencers, etc.
They will both be for daytime fine weather use only, so no need for too many practicalities!
