Bit late for JJB, but another option 'may' be to get a SW Motech Street Rack.  I say 'may' only because I assume SW Motech have designed their parts to fit together so their Street Rack might fit with their Tail Tidy.  I only have the Street Rack so can't verify.

The advantage of the street rack is you can buy adapter plates to fit top boxes and other luggage.  I have atapter plates for my large Givi top box and my small BMW (Shad) top box.

And once the adapter plates are removed (tool free in seonds) the rack itself is small and discreet.

Seat is sold! thanks for the interest.

For those just dealing with notchiness, one bit I found interesting in another thread was that when Jggpossum had the defective original clutch replaced on warranty, he was advised by the dealer service dept not to use the quick shifter for the first ~1,000km/600mi with the new clutch to allow the new plates and friction discs to bed in smoothly.  It makes some sense to me that the friction material could experience some uneven wear when you bang up and down with the quick shifter with a fresh clutch that is fully engaged. It would be interesting to see if quick-shifter equipped bikes report more clutch troubles than those without.

The other thing to look out for is that the clutch cable adjustment is more critical on this bike than any other I've dealt with, the clutch feel is much worse if lever play is less than spec. Mine needed a big adjustment around 2000 miles because there was almost no play left, even though it was in spec at the 600mi service. It seems like this clutch has a lot of break in wear, after that first adjustment the play has stayed consistent, indicating that the rate of wear has slowed. I'm now at 8500 miles.

Shadey, did you buy it?

noticed this "notchy" clutch on the demo bike I rode yesterday - thought it was a dodgy cable.  Hope mine doesn't suffer when I get it....................
