My friends 1995 KQ hit 48 with 2 people on it(flat ground) Its stock, with 1 person, im guessing it will do atleast 55mph

 

fast enough for a utility

 

Not that it really matters, seeing as though it is a utility quad, but, all kidding aside, I have had my 2000 King Quad up to 54 MPH, on very hard packed ground, and it was pretty level. I was just keeping up with a '97 Honda 300 4x4, and a few Scramblers, but they were losing my in the dust...
I don't believe in doing anything to my Quad, because I haven't found anything wrong with it yet...

Long live the King, Baby!

Don't worry Bill... You've got the point, I'll take the rear... At least if there's somethin' up front that I don't need to run into, you will surely see it before I do... And we all know you have ESP (N)... We rely on you to keep us outta trouble. It's just that, some times it don't work too well... Don't go so fast next time Bill! I still have the GPS...

I have clocked my dad's King Quad at 52mph on Flat black top and 60mph down the steep hill on the hard park road. The rev limiter never hit. I was very happy that I hit 60 on the slow quad. This Quad Rocks anyway! This machine has very lack of top end power. I only could hit 35 on sightly up hill that it.
Hope this help you.
