Difference between 1984 vf1000re and 1985 vf1000rf frames

hi, I’m new to this forum and I have a 1984 vf1000re, my question is : is there any difference between the 1984 vf1000re and the 1985 vf1000rf frames? any help appreciated…

Welcome,three main differences I can think of are
1 RF has brackets on the front frame rails to bolt to the front head
2 RF right frame rail is curved to allow for the extra width of the rear cylinder head
3 lower mounts for the fairing on the bottom rails are further forward on the RF
There may be others
best regards Bif

I would perhaps also mention the coolant, which is fed through the left front removable part of the frame on the RE, but not on the RF, which does this via a hose.
Correct me please, if I should be wrong!

Excellent ok that’s very useful Bif, so if there are brackets on the RF frame rails for the front head that would mean it would be apparent if there was a combination of an RE engine fitted to an RF frame… I shall have a closer look, many thanks

Also useful JK, it gives me a cross ref, appreciate the information…
many thanks, Richard

And the width for the upper mounting of the rear shock absorber differs. There are welded washers in 85/86 frame

appreciate the information Faxe, thanks
