F2 to F3?

if this is the tail you are referring to then its almost identical to the 95/96 tail.
you can get the whole 97/98 tail and upconvert it.
you will need 3 tail fairing pieces, the seat, the rear taillight and mounting brackets.
if you chose to do a newer cbr tail aside from that, it will require you to modify the subframe.

I dont really care for the r1 tail on a cbr either, it seems to sit too low. The forks and swing arm are different on the f3 but since you already have that swaping them out shouldnt be too much of a a issue
