Aside from the friggin rocker box leaks (both repaired with Cometic gaskets); my '08 1200 just flipped 20,000 with no problems at all. Bike was bought two years ago September 17th.
I have 31k on my '04 XLC. Right now I'm changing the stator, and I've had some problems with both the front and rear brake light switches. Otherwise just routine maintenance.
I bought my '06 XLC around the Christmas 2010. Had 7000 +/-. Now 11,000 +/- in 9 months. No problems. Just ordered new seat, La Rosa solo and a spring kit. Looking forward to making some changes, ie. ape hangers, taller sissy bar, change tail light and tag location.
About 12K on my '08. Needed rocker cover gaskets a known issue and recently rear wheel bearings also apparently now an issue across the line.
Drive mine daily until the snow flies.

Almost 12K on my '11 XR. Most of those were "fun" miles, so if nothings popped loose or sheared off yet, I don't expect it to. Just oil changes and tires, and more tires.
