Larger Discs for Z750

Hi where can I get some larger front discs/rotors for a z750 from 1982 ? this is for a race bike project. What option are available?
Does anything else have the same bolt pattern

Is this a 4 cylinder? I doubt there is anything modern that will bolt on as the pattern and diameter is unusual.. EBC makes aftermarket disks that will bolt on and work well that are stock size. MD4010LS and MD4010RS one for each side. I believe the ZG1200 also used the same disc pattern and the disks may be slightly bigger but I cannot confirm that.

This rotor is listed for $66 but is normally like $150. I had this happen to me before on amazon while looking at EBC disks. I scored a set of EBC KZ650 rotors earlier this year for $50 shipped brand new from amazon in the box and immediately sold them for WAY more.

Yes for the 4 cylinder. I have dropped EBC an email to ask. may have to be custom then (

ZG1200 disc size appears to be 260mm

You'll get better results by ugrading the calipers than the discs. Stock khi disc's are pretty good if the surface is not shot. Easily re ground smootb again. If your after saving un sprung weight twin disc set ups use thinner discs and are considerably lighter.
