I'm heavily leaning towards picking up a plated KTM 200 EXC 2-stroke for my next project. Think it would be a blast in the woods....and with sumo wheels on the karting tracks.[/QUOTE]
Can heartily recommend the 200 2-stroke idea. After a string of dual-purpose Yamahas and a couple of KDX's, my last off-roader was a Gas-Gas EC200. Absolutely primo woods , forest, single-track bike. A little less hard-edged than the EXC, but in a similar ball-park.
A complete rocket ship once jetted correctly, and ultra-reliable.
