I have a VFR750 rear on my GSXR...but can't find a reasonably priced caliper. I have a complete VFR800 rear end laying aside. Can I use the caliper hanger and caliper from the 800 on the 750?
Since no one seems to know: Yes. You can use the 800 ('98 ABS if it matters) hanger and caliper with the 750 rotating setup. You have to fabricate a new brake arm and you might not get 360* of rotation so be mindful of where your setup is when you make your new arm.
