Just bought a 93 KDX 200. I really like the bike, but it is a little too tall for me (I'm 5'-8" tall). I am a woods rider used to Honda XR200 on which I can touch both feet flat in rough, twisty and steep terrain of southwest VA. Does the monoshock spring adjust to drop the rear and how about sliding up the forks until they touch the bars? What about aftermarket seats? Are any thinner ones available?
