I just took my S50 on a 4,000 mile roundtrip to/from Chicago/Colorado, and it handled beautifully. Plenty of zip to get around traffic on the expressway, and nice handling and performance in the mountains. Keep in mind, however, that it´s pretty low to the ground and therefore tight turns on those mountain roads might have you scraping pegs at higher speeds. (Slow down for those instead.) :-) I loved the S50´s performance on the trip!
