I just have to say, how much I am in love with my xchallenge. I recently got it, and had only put about 700 miles on it, all short trips. But I just got back from just about a 275 mile trip today, and besides the stock seat needing to be changed, the bike performed as well if not better than I ever could have imagined! All but maybe five miles were pavement, ranging from 20 mph to almost 80. The thing was so smooth, hit my feet a few times in the corners, I was truly amazed. This bike certainly does seem to be a do it all bike, from fairly technical stuff, to highway riding. I couldn't be happier!
