I know these KDX's are cute as bugs,they run for ever and harm nothing in the process.
Having said that Ive had 3 KTM200's, a 2001,2004 and a 2008. Its honestly hard to tell if the engine is turned on riding a KDX around after riding a good running orange 200. Not that there's anything wrong with slow and heavy 200 2 strokes.
Riding a 300 currently but looking for a good 200.
