These are some of the best trail bikes ever made. Don't be afraid to buy one of the older XR250's.... as long as it hasn't been abused. Mods are easy and parts are plentiful and relatively inexpensive. Also one of the best off grid / hunting / survival bikes you can get! 70+ mpg, quiet, will climb a wall and still keep up with most traffic. Tall seat height of 37 inches makes this best suited for rides 5'11" or taller.
