I used to be into dirt bikes (for 38 years) but, a bad accident convinced me to switch to a Teryx. I ride desert, and mountain trails. It is not as much fun as the KTM 520 but seems a lot safer. So far I have had it to the desert (several times) and to Moab for a week, and in the high sierras on some pretty rough trails. Is there anyone that has put taller tires, and wheels on one (when in the rock crawling mode)? My only complaint is the "bottoming out" on the rocky stuff.
