does a 2002 f4i engine fit in a f4 frame?
 

im rebuilding a 2002 cbr 600 f4i and i have been looking around at frames and i hve some questions.. i got the engine(2002 cbr 600 f4i) for free from my family but i need to get a new frame. i got a offer from a guy selling his f4 frame and he says they fit but i wanted to check some more and find out for sure before i buy it.. and if it does fit can i still fit on a f4i rear sub frame? thanks for any help any one can offer

yes direct fit im pretty sure

Im pretty sure the sub frame will fit as well. You might have to make minor adjustments. You will have to get new rear fairing and seat. The only thing Im not sure about is how all the electronics will fit to run the FI. Also just make sure that the guy has the title and its clean if you do go for the F4 frame.

the frames are the same from 99 - 06!

^ +1 direct fit
