A later model model stock KDX200 makes 26 rear wheel HP off the show room floor. An uncorked one (jetted right and w/ opened up exhaust) gets you to near 30 HP. This will cost you <$200 for the Gnarly expansion chamber. One that has a RB Designs modded carb and head (another $200) gets you at 35 HP. It is alot cheaper to do this to that than to get a KTM200. The KTM suspension rocks though.

Fully modified KDX makes good power though,its a lot of mods . KTM's new 150 is making almost 35hp,trick little bike.
