i feel ya. the front forks on the chassis i picked up are startin to pit. so i would be using my 500 front forks. some of the bearings in the rear are seased. was a pain in the arss to get the bottom bolt out of the linkege to take the rear shock off. i picked it up hoping that it was indeed a 250 frame i was going to use a bunch off my 500. judging by the responsis im getting im prob just gonna part it.

Similar in that they are both painted green :-D beyond that they are completely different where the motor sits in the cradle. I bought one years ago thinking they would be close enough, there were to many things that diodn't work for me, I knew it was going to be a huge job so I set aside the 125 frame and went with a 250. I'm now using the 125 frame for my KDX hybrid conversion. was it me I'd use the 250 frame and make life easy on yourself.

i thought it wouldnt even be close as well, but when i placed my motor in the frame the bottom mount as well as the swing arm bolt lined right up. if i cut the the swing arm it would bolt right up.

There is one critical measurement that you have not mentioned, The countershaft center has to line up with the center of the swingarm bolt which in theory you also have to have the swingarm at the midpoint of its stroke and the axle would also line up. the countershaft and the swingarm most defineately have to line up the swingarm has to be very close otherwise the chain will either be way to loose or to tight, by aligning them you reach a compromise. I don't remember exactly why I didn't use the 125 frame, but there must have been one, maybe I was lazy and didn't want to do the extra work.

hmm good point.. i deff did forget about that. couldnt that be adjusted by the mount hight? well to a certain extent? im gonna take a look at that tonight. if its off by a lot im just gonna keep what i can and part the rest for the 250/500 build. it would be freakin awesome to have a 500 in a 125 frame but i dont know if its worth the work.
