This will be the short version. After breaking in the 650 Sand Viper, I turned to my daughter at the end of the day and said "Do you want to see what this thing can do?"
The area is high desert, the route we chose was about 5 miles total and consisted of a high speed power line road, whoop infested trail, typical desert trail, a mix of uneven and rocky terrian, and ended it with a wild ride in probably the best sand wash trail I've seen in a while. Only one rule, AS FAST AS IT CAN GO.
All I have to say is, it should have broke. It not only did not break, it was ready to do it again. All I can say is WOW.
