I need a measurement

I'm needing a measurement of the rotor spacing on the front of a dual disc setup on a kz1000. If someone can get me an outside to outside measurement of the disc I'd be grateful. Every thing I have is either late model suspension or single disc.
Thanks

1982 KZ1000J2 - 115mm Outside to Outside.

Thanks, I'm betting a spoked wheel with dual disc is the same, can anyone confirm this?

NP... and I can't confirm, but it makes sense it would be the same as the caliper mounts are identical.

1981 KZ1000 M1 CSR with spoke wheels: 4.5 inches or 114.3mm
The conversion from inches to mm isn't exact so I would say that is the same as 115mm. Just only had a ruler with inches.
