I'm interested in getting a bike. I live out in the boondocks, so a trip to town is 40 miles one way. A trip to an actual city is 100 miles one way. Most of the miles are on I 25. I know you recommend starting on a 250, but should I be looking at a 500 or something a little b***** since I have so many highway miles? Are these bikes comfortable to ride long distances? If I lived in town, I'd go with a 250.
