the KDX rips, its the "clark kent " of dirt bikes, mild mannered in the tight twisty stuff, but get it in the wide open and it rips like a full mx'er with the right mods its way faster than a 125, plus alot more low end power, and in a drag ive finished just about 1or 2 bike lenths behind most 250's thus giving the bike its name the giant killer, everyone that climbs aboard my KDX 200 comes back with a big smile 125 guys cant beleive the bottom end power, and 250 guys are amazed at the top end for the bike only being a 200, both my brother and i have modified 200's and have only good things to say about the KDX, but then again, come to a KDX forum and ask how good it is, your gonna get this kinda response!, just ride one!!!
