I have a 570, and all I can say is it has performed very well for me. Climbed every hill I have had the nerve to try it on and haven't once wished I had more power. I live at high altitude over 5k feet and regularly head up to the mountains over 7k feet....again, I have yet to experience a lack of power to tackle any obstacle a trail has had to offer. I hope you get the opportunity to test ride one. Its not the monster the 850s or the 1000s are, but it has plenty of power for me and does great on the trails.

 

Finally got to test drive a 570 SP and a 850 SP...... and my mind is made up........ an 850 SP is one I like the best... The engine braking is lot more pronounced on the 570, not so much on the 850... I think that part of it made me go for the 850.. Thanks for all the advice..

 

After you get to ride it awhile let us know what you think.

 

Congratulations on the new quad.
