I took my old 1300S in on a trailer, and rolled it right up to the lift. Two of them lifted the back-end up, and the third pulled out the tire/wheel (removed one of the mufflers, too). They installed a new tube, then put it back together. I don't think they made much money, but it did happen twice in three weeks (construction down the alley).
I've only had one flat on the 1800R, (on the back, of course), and it was in the sidewall; New tire that time... over $200 (but I moved upto a 200mm tire, which was actually less $ than the 180).
