A prarie 650 will run 62 with mid 20's inch tire(not really sure what they are). I have heard that a prarie has an electronic limiter. Not a rev limiter or something like that. Not really sure on that.

 

The fastest I've driven my S is 52 mph. I've tried to get more out it but that's all it'll give.

 

I was on an old Honda and made it to around 50 MPH running next to a pick-up - racing checking top speed. Trouble was that at high speed the tires behaved very erratically and when combined with the solid rear axle the ATV things got uncontrollable in a hurry. I ended up flipping the damned thing when I tried to decelerate. Sliding down the middle of the highway at 50 MPH wearing just jeans and t-shirt ruins your whole day. Spending a few hours in the ER with the medical types picking gravel out of your road rash is no picnic either by the way.

Guess they were serious when they said not to ride on pavement.

 

You know somebody has to say it. Don't ride your quad down the road, stay on the trails that your are supposed to. AlaskaBoy.

 

Napa mod, factory tires, factory timing, factory jetting;
Kawasaki 2003 Prairie 650, green.
I've had mine up to 35-38 hard to tell wasnt looking at speedometer.
But I understand that the red ones do a bit quicker

 

48 for this Prairie down a super smooth, downhill, pavement. If I start to wreck it, I'll just step off. It's the only one with a speedo, but as others have cited their 450 Foremans at 50 or so and I'm just a little slower than my buddy on his, this must be close.
