04 Speedmaster with 25,000 and 04 America with about 15,000 miles on them. Both have been trouble free, just regular maintenance. We rode our bikes to Florida and back this summer, about 3,000 miles total with the running around down there included. Rode through heavy rains here and there, neither bike ever skipped a beat. When I first got my SM we rode 2 up in heavy rain to Laconia NH rode there for a week then home again in blistering heat. We got burned but the bikes never skipped a beat (my friend was on an America) I have done many other rides too and would think nothing of hopping on our bikes to ride anywhere. Yellowstone park is in the near future when I can swing the time and cost.
