Got an 05 summit highmark x 1000 sdi. Love it, going to keep it. Put $10 000.00 into your xp to keep up with it. Learn to counter steer and ride them and they are more maneuverable than most others, for me anyway. A couple buddy's took my 1000 for a rip and couldn't believe how easy it was to maneuver. Long live the 1000 or just sell them to me cheep so i have extra parts.
