Maybe AJ will chime in here, but I wonder what the best years were for the 500 swaps in those frames. It is possible that that rigidity would be tamed or vice-versa with the 5s power. Or might make it a horrible ride.
I always
thought, though, that I'd like a stiffer ride. Kinda like riding a meat cleaver vs one of those old floppy wood saws that hillbillies make music with.
You don't see surgeons working with those things, nowadays anyway.
You know, once the ergos fit, it's like a scalpel, or something... But, I'm faster on my '00 KX5 than I was on my '99 CR250 in all terrain. My 5 just out-handles it, and maybe there was something wrong with my forks, but it's true...
That makes me wonder how that '09KX5AF handles... I wanna ride one,
BAD!!!
