Since I started this thread, I feel obligated to report that I sold my (2nd) H-series KDX200 back in December of 2012. I wasn't even trying to sell it! I was approached by someone who knew that I owned a street legal KDX200.
I replaced it with a 2012 KTM 350 EXC. I hope that the EXC is as reliable, nimble, and fun as the KDX was.
I will always be a KDX lover. With just a pipe and a reed cage, they are fun, reliable, capable, and affordable, and I would never hesitate to recommend one to a friend.
Street bikes for the street. Dirt bikes for the dirt. Let's keep it that way.
