I use to work at a KTM, Yamaha, and Suzuki dealership. If you buy the KTM (which I love the 200 EXC). The first thing you should do is disasseamble the entire frame. And Lubricate every bearing and bushing. I use a product like Maxima or Bel Ray grease. Change the oil, just skip the break-in oil. Go right too a ultra high grade synthitc in the trans. I do not use the factory shell oil. It is hard to get, and break down very fast. Other then that. Buy a spare shifter or 3, safter wire everything, and ride the crap out of it. Kill The Mud, Konquer The Mountian, Kick The Mother. You call it!
