Mine's been to 65 mph with 25" Mudlites and I'm 6'9", 300 lbs

 

I could only do 61 mph on the speedo on my P700 breaking it in. Had to drive 55 miles to find that level stretch of paved road. Hope it gets faster as it breaks in more....only had about 30 miles on it at the time.

The highest I've seen my '02P650 (with mud tires) is 63 mph.

My advice is to hit a measured distance at top speed on the flat, with a stopwatch, to really know what's up.

 

gentelmen, won thing you better lurn, is when your makeing all these purchases of high dollar atv's on the asumption of wich won has the most top speed. there are to many things that can affect the top speed. like,are the belts loose or worn more than the other atv's. is the jetting done right on both. is riders close to same weight. these are just a few of the things but certanly not close to all. and remember one other thing. don't let the" dealer " convince you one way or the other.

 

alltoos is right if you're riding in any kind of hills at all. Top end means squat, getting to top end quick is where it's at.

If you're riding in flatlands, I'd say half of the atv fun is just not available compared to mtn trail riding. No offense to anyone, that's just the way it is.

 

I have only seen 66 on mine and that was more than enough!My 02 650 Prairie STOCK always takes our groups Grizzs...straight or in turns!!!The grizz is a good bike but not one for someone who likes to ride fast on twisty trails.
