I am looking to grab a bike over this summer and am wondering if the bug XR would be the right bike (I have also been looking at KTM two-strokes). This bike will be used daily as a short commute (5 miles or less) bike durring the week, and then I could throw another set of wheels on it so my dad could ride it off road with us. He is ~250 lbs and I "stole" his 450 by riding it alot get starting to race it. He wants a bike with plenty of power off road, but something that will be comfortable and not beat him up like an MX bike. How will the XR fit this role? I am currently looking at the l model, is that what I should be looking for? Finally, what year ranges should I look for? I am willing to spend between $2000 and $3000.
