Well, it does ok. It doesn't have the "wheel spin" to do amazing in the dunes. I was able to go 90% of the places the razor 900 and 1000 went. Its hard to start accelerating at the bottom of the hill, i need a bit more of a run than the other guys in Razors. I would say the sand tires front and rear increased my acceleration at least 3 fold, increased my climbing and top speed just a little. These are Dunes here in Utah, and there is the "sand Mtn" which is a HUGE hill climb, i can do it if i put it in 4 diff lock, and i summit at about 10mph, while the other guys summit at like 35mph, so it just doesn't have the "wheel spin" to keep the speed up on hills over 30-45 yards. Anything under that and i keep up with the others JUST FINE>
No pucker factor, ive ridden since i was 5 years old. I knew what i was doing and how to jump it. the first jump was a good 2-3 feet higher, i really launched it and that hurt a little on landing.
Cant seem to find any after market shocks.
