I have an idea to use a 250f frame and use a kx125 engine and suspension. All I have to go off right now are two pics of a KX144AF built in Italy. I can tell from the pics that they used the 125 subframe, rear numberplates, rear fender, and airbox. Does anyone know if they used a 250F seat? Also, does anyone know if i'll have to cut the cradle to accept the larger two smoker exhaust? Any comments are appreciated.
