Not sure if the 94 250 has the same bearings size with out looking up the parts sizes as a kx250 05 to 08 250 kx but i do know i fitting kx450 14 clamps on one of my 05 250 with a 19 front forks and wheel and brake set up , and the only mod was to extend the steering lock on the frame, personally im not keen on any of the showa air forks and would get the later showa 49 spring forks or earlier kyb air fork or spring forks.There just easier to get better performance out of and tune.
