    f3+f4i subframes


    for you older cbr pro's, can you tell me if the subframes on the 600f3s are the same as the ones on the f4i with the split seat? i believe the ones with the split seat are from 01-03? ive seen a few people swap the tail from an f4i to an f3 but none mentioned anything about the subframes. just wondering if the plastic will swap cleanly or if i will have to make a new subframe.

    F4i subframe is required.

    You can pick up a perfect condition f4i subframe for about $100 on ebay. That would be the route I would go if I were you.

    i see, so the f4i subframe will bolt up to the f3? i must have misunderstood you for saying that the frame wont bolt up.

    also i think 01-03 had the split seat and after that they went back to the fat banana seat. Are all the f4i subframes the same or do i need to find a subframe within the split seat years?

    I believe some customization is required. I was looking into this when I had my F2(same frame/subframe as your bike) and there was some welding required. Let me look back on the cbr forum I was on. I know there's a "how to" writeup somewhere

    f3+f4i subframes

    so basically what i have seen is that some people use the f4i subframe and others modify the f3 frame. guess ill just get the plastic first, fit it and go from there. thanks for the help
