You guys are not hoping for to much maybe? I rode a 2003 800cc twin Suzuki Marauder street bike and it only weights 465lb and could only hit the high 90s and that is on a flat paved freeway.

You would think a 700lb 850 twin ATV with 4 balloon tires and on a dirt road would be alot slower.

 

I have not had it WOT in a while. Have not had the open area to open it up. I will over this weekend so I will see if it is any better. I will be playing at over 9000'. I know altitude will have some affect but I expect a little more top end. It does get to 40+ really fast. It is just the top end that seems out of line with what other seem to be getting.

 

Yes, My 850 XP Screams to 40mph, but dies after that... it takes FOREVER to climb to 63mph...what should the 850 max rev at? I was thinking like 8200rpms???

 

i just had my 800 up to 60 and let off, so i would guess you have an issues w/ it some how. maybe ask the dealer.

 

I haven't had the throttle at max on my 850 yet but I have had it up to 64mph thus far. I test drove a 550 and I maxed out about 65mph. Neither of these speeds were taken from a GPS, just the speedometer itself. Also both machines were stock with myself and gear totaling 220-240 lbs.

 

Yea there is something wrong for sure,here is a video of mine bone stock when I had stock tires on it and it only had alittle over 100 miles on it.

YouTube - polaris 850xp top end run

 

Ya I think I'll run 1 more tank of gas through it, the break in period should be over by then and the computer should allow more power...at least thats what my dealer tells me...

 

Do you know what yours rev's out at? Mine will only rev to 7090rpms...
