850 Max vs 1000 max

Hello!

Im planning on throwing down on a 2up atv in the next month or so and I was wondering for those who have them or ridden them, is there a noticeable difference between the 850 max and the 1000? Ive ridden a new 850 and it had good power, just didn’t blow me away. Is there that much more get up in the 1000?

Just would like anyone’s input before I decide on a bike to buy.

I do love power and ride in sand regularly FYI.

I am also considering a Polaris 1000 touring, but no one has one and would have to be ordered.
