In fact, I'd look at using the KX125 chassis if I had the opportunity.

I tried this, it does not work.
The frame cradle is much much too small.
I tried using a 2004 KX125 rolling chassis for my first attempt at a hybrid. That being said sure you COULD make it work, its only metal after all. But its not a simple affair as using a 250 2stroke frame.

:-D 8-) ... 250 and 500 always used the same framerails.... 125motor is much smaller and also the frame rails are made for the smaller engine... you could bring a 125 in a 250/500 chassis, but not the bigger engine in the 125 frame , without cutting and modifying the frame rails... big diference between 125 and 500 except the motors were ever the frame rails since 1990... all other parts are 99% the same

jcm3,
Hey again - I just left you a note on your other thread.
I owned a 89 KX 500 and I currently own a 1990 model. From 1989 - 2004 (last year of the K5) all the motors are the same.
The only changes, other than "Bold New Graphics" after 89 came in 1994, when they changed the triple trees to accommodate the newer KX250 forks, and changed the brake caliper mount on the swing arm to accommodate the newer KX 250 rear caliper.
Other than those few changes, everything else on those bikes were exactly same for all those years.
