People, I hate to admit it, but I think the environmentalists will have a say in this deal. The 2-stroke is fading away because of its pollution (on the environmentalist end), and because of the performance characteristics. Riders like 4 stroke bottom end power because it's more forgiving. KDX is not in popular racing classes.
I'd personally like to see the KDX continued, but I have a feeling 2006 will be the last year, and I'll be buying 12 packed in cosmoline (if I could just win the lottery).
Otherwise, I think we're stuck learning how to tweak and tune and rebuild 4 strokes. Something to think about for college for the young folks out there. KLX is the model that will probably replace it. I hope they never quit at least making parts for the KDX...ever.
Anyone have trails being closed down in their riding areas? I used to ride in Northern Colorado...for several years running, family camping there for 50+. They have closed at least 1 trail for erosion and watershed concerns, and plan to close more next season. Further, the USFS has new policy changes on the make for US forest land. So far the only discussion to the FS website I've seen is from people in support of preserving these watershed boundaries and preventing erosion. I haven't seen a lot of argument about how many trail riders respect the land and don't tear it up or deviate from designated trails, let alone the other side of the impact of OHV's on watershed boundaries...
