I picked up a 97 Honda fourtrax 300. Air cooled, two wheel drive, easy to work on, tough as nails, and it aint BIG as a tank! I can get between trees, runs up and down my rocky hills with no trouble. So, for my terrain, it's perfect. Now, i do have a diesel John Deere XUV Gator being delivered this week for the bigger places i hunt.
x2 on the size...when I bought the quadrunner I bought the 500 because it was still one of the smaller sized wheelers...getting in the thick bruskhand trying to maneuver is tuff enough with this one so I can just imagine what it would be like with the bigger ones...
