I was thinking about getting one. Right now i have a predator, and I have upgrades for it. So right now I'm accustomed to tons of power, torque, and speed. What can I expect for the MXR? What's the stock top speed? Are they a good option for racing? My main concern is durability. I'm looking for the quad that i can ride tough, but as long as i keep up on the maintenance it will last a lifetime! So any opinions and experiences would be greatly appreciated!
