alext Posted November 9, 2020 Report Share Posted November 9, 2020 Identifying front forks.... I have a set of what i thought were CBR600F2 forks - they deffo have F2 bottoms, BUT, they also have damping and preload adjustment, which I thought only came with the F3. what Im trying to do is swap the bottoms for the F3 Items I have so my brake calipers fit. they are in good nick, and the oil in them is very clean - so not original, and Im wondering if someone has altready swapped the F2 internals for F3 stuff cos its better! Any suggestions on correctly identifying what I have?? plus, more concerningly...... previous owner syndrome has hit the bolt in the bottom of the leg, its completely chewed up and I cant get an allen-key to grip - any suggestions on how to remove this bolt?

martzxr Posted November 9, 2020 Report Share Posted November 9, 2020 What you probably have is late f2 forks which had what you described. Although the tops look similar the internals are different, the f3's have a long damper rod where as the late f2's have a very short one. Not sure if you can put the f3 bottoms onto your forks Quote Link to comment Share on other sites More sharing options...
alext Posted November 10, 2020 Author Report Share Posted November 10, 2020 I know you can put the F3 stuff into the F2 without any mods, so surely it must work the other way round? if not Ill be looking for a dead set of f3 forks........

alext Posted November 11, 2020 Author Report Share Posted November 11, 2020 it all looks to have swapped OK - everything fitted in the same way or position in the F3 bottoms as the F2 ones. waiting on seals and seal-driver to complete the job now. 3 Quote Link to comment Share on other sites More sharing options...
martzxr Posted November 11, 2020 Report Share Posted November 11, 2020 If you are keeping the f2 wheel just check the calipers sit in the right position on the disc as I think the f3 had bigger disc's Quote Link to comment Share on other sites More sharing options...
