I just bought a '91-'94 FZR 1000 complete front end & complete rear swingarm/shock/brake & rear master cyl to play around with. I was gonna give my machinist a stock rear & the rear FZR wheel to see if he can come up w/an economical mod. From the looks of the wheel width, the swingarm will need to be notched if this is going to work. Since i already have a matching front, I am hoping to have a matching pair of wheels when I am done. I was trying to avoid the front end switchout as the VMax front end is ~1 3/4" lomger than the '91-'94 FZR 1K front, which would probably cause all-kinds of cornering clearance issues when using the FZR & I was not really wanting to buy new longer downtubes to make it work.
Oh yeah, since the downtubes are both 43mm, I may just swap the '91-'94 FZR 1000 front end & brakes into the stock triple trees for a quick daylight "road feasibility study" to check on the cornering clearance. If I like how it works, then I can always change-out the downtubes for longer replacements & fab a headlightr mount.
