Frames are the same.

There is a difference between the 250 gearbox ratios and the 450/525. Really alot of things are different between the 250 and the 450/525's. The actual engine cases are the same I believe.

I don't think they had the 400 EXC in 03???????

There is some good information on KTMTalk at the top of the RFS section. Pinned Evolution of the RFS. Gives all the changes of the Motor and Chassis throughout the years.
