I'd be staggered if they are different - looks like the identical panniers on R-R / R-RT and K-GT (didn't the ST die under the weight of shame for its oh-so-ugly headlight?).
Anyway, when I bought (2 years ago) the salesman put bags from an RT on the the demo to show the "fit" (they did) and I have the protection strips from the RT / GT over the colour-coded paint on my pannier lids. http://picasaweb.google.com/billstanhop ... 0050389154
2 pieces of gratutitous advice (coz I can't resist):
1 - these are easily the best luggage option: they are simply unnoticeable up to (and over ) 200km/h .. 125pmh
2 - take the trouble to get them keyed with you ignition (see a thread hereabouts on NOT doing that the hard way)
I'll echo that thought that they should fit. When I got my bike last year they didn't have the bags in so they just took a set off to put on mine for the test ride. Also it looks like AS Cycles ? has the city lids now too!! They are on their web site and as soon as I have the cash they will be on mine.
