I inherited my '03 with hand-guards and they seem to fit fine, it's gone through 6 MOTs and no one ever mentioned anything. No idea of the make but they look very plasticky, I guess they 'just about' touch the fairing but it's never given me an issue. Since I changed to Renthals they've not been secured to the ends of the bars, just on the brake/clutch bolts, but they don't flap around much.
I can't imagine riding without them in winter, even with my heated grips... I'll try and get some photos over the weekend.
