Re: 2004-2007 Fairings and subframe on a 1993 cbr900???
What a coincidence, I'm currently putting a 06 1000rr tail on my 929 subframe (similar ordeal)
I don't know about successfully putting the 04 subframe on the frame of your 900 since the mounting points are way different... the 900 suframe mounts both high and low on the main frame and the tail juts upward (large angle on the mounting points)... Where as the 04 1000rr tail has a mounting points close together on the subframe and the tail juts almost straight out from the 1000rr main frame see pics...
See how the subframe juts out a nearly a horizontal angle?
