Im pretty sure 18/20 hp is what they have stock. They arent fast but make great little woods bikes,just gotta buzz em and row the gears to make em move well.
A KTM200 might approach 35 hp at max buzz and weighs less and less the newer it is.
Google KDX info and some kind of power output will pop up somewhere.
I have no idea how much power this little pig will produce. It's got all the good stuff, and is light and kind of high strung. All I know is that I twisted it the smallest bit on in third. and up she came. That's plenty good for me. I don't need no dyno.
37 is claimed here:http://www.motorcyclespecs.co.za/mod...dx200%2005.htm
