1.Ground clearance, mid-range and top end power, comfortable ride, very nimble considering its' weight, fit and finish, EFI!!, Honda reliability.
2. My only real issue with it is that 3rd gear seems a little too tall, so the gearing is off a bit there, especially in trail riding conditions. The black plastic gets trashed VERY fast too, but that would be the case with ANY black quad.
3. Gearing #1 (at least in third). For the price it sells for, it should have fully adjustable shocks on all four corners.
4. I bought mine when they first hit the floor, so I paid full retail PLUS setup, so I did not get a good deal at all. I didn't care though, I had been waiting on it for months. I live in Washington state.
The XX is an awesome quad...ESPECIALLY if you are a trail rider. If you are a sand guy, I'd say look elsewhere.
