depends on your rear sprocket. I know the 03 yz85 on stock sprockets will run out at about 75mph.

Honestly, with stock sprockets, i wouldnt say much more than 60mph. You can change that with gearing though (make the front larger and rear smaller).

Why would anyone want to go 60 mph on a KX85? Death wish?:mad:

They will go much faster if you put in a new power band.

(I figure that answer fits the post)

Ok guys, I had a 03' KX 85 pure stock, except I had to put a bigger sprocket on the back b/c it was geared so high and I needed to gear it down some. (and that didn't even help) But I had one of my friends drag race it and it was in the 6 second area, give or take a thousandth of a second, and that wasn't even topped out it was only half of 6th gear pullin a wheelier from start to finish.

You can do a lot with these bikes, wouldnt be suprised if you could get an 85 up to 60, but no faster than that.

It depends on way too many factors to be answered here, as you can probably see from all of the replies. Gearing, tires size, tire wear, surface you are running on, condition of the engine, everything effects top speed. Your bike might do 50 mph, it might do 70 mph. No one on the internet can tell you for sure.

Got a GPS unit you can use? Throw it in your pocket and let her rip.

Get one of those Hot Wheels radar guns ( about $40) and try that!
