Are you looking for rotors that fit a CB750 hub? And what OD do you need? 300mm? 296mm?

Yes, it needs to be the CB750 bolt pattern and center hole and the right size bolt holes. They are going on my Triumph which is light by standards and so I can run a smaller dual disc front set up. All Metal Gear had was 275 dia., 56mm center hole, 78mm 6 x8.5mm bolt circle, 17mm offset, and 5mm thick. The bolt hole size is .5mm too large, but can be dealt with. The 17mm offset might be tad too much, but may just work.

cb750 pattern is 80mm X 6, he's using vfr400 wheels he's said which are 74mm X6.

if it were cb750 bolt pattern early FZR600 or fzr1000 rotors would be correct pattern and I believe 10mm offset.

Right. He was answering my question, sorry for the thread jack. I asked because I've done the conversion on CB750s and GL1000s. But you answered my question from before with the POs pattern. As far as the FZR rotors, they are 6 x 800mm, but 298mm. YZF600R are as well, but 95/96 YZFs have a 300mm OD.

yeah, I've had some fzr600 rotors in hand that were 298mm and some fzr1000 ones that were 320mm. I see no issue using a 298mm rotor on something that originally used 300mm rotors, there's usually space between edge of pads and edge of rotor so I doubt there'd be funky pad wear in that 1mm radius difference.
