Thanks Tuck,
We seem to be thinking along the same lines, I believe the 125 would be just right. It's hard to make the right call with him, he out-grows everything so quickly, not your average 10y.o.. Want to give him the same great memories of riding the woods, that my dad gave me. Of course we must grow the next generation of the sport, so we don't lose it along the way, something we forget sometimes.
Now the question is, what about the old man? A re-entry rider, tons of street cred, but haven't gotten dirty in many a year. And at 6'4" and 250lbs, everything seem miniature. A KDX might just be the way to go in the short term, but would love to have the kx5 long term. Thanks, see you all again soon...
