Ok guys I am looking to getting back into riding in the dirt. I currently ride in the street. I used to ride when I was younger on a friends bike. I am 5'10 and around 220. (played football for a long time) I want to do mostly trail riding and playing around in the fields. I might look into getting into MX once I get my skills up. What kind of bike should I look into getting. I was thinking either a XR250 or TTR250. The one problem that I have is that it seems that most of the bikes out there are too tall. Can that be fixed?
