Does anyone know what parts, if any, are interchangable between the F3 and F4? I need a front fork for a '96 CBR600F3, we found an F4 at the junk yard with a good fork, will it fit? Anything you can tell me about similarities with parts would help.

 

It will fit, but you need the f4 front calipers and triple clamps. I think you can still use your f3 wheel though.

 

The forks by themselves will not fit. F3 is 41mm, F4 is 43mm.

 

forks are way different
