Hi!
I have a question for you:

Are the front brake discs the same on the gpz 750 and the gpz 1100 from 1983?

I found websites who sell the same brake disc for gpz 1100 and gpz 750 turbo.
And I believe that the turbo and non-turbo has the same front discs?

The front wheel are the same on the gpz750 and the 1100 so the disc should fit?

If anyone knows the answer I would be very glad.

/Karl

Kawasaki Brake Disc Measurements

Z1100A1-A3 shaft. Front disc =236 mm, rear disc= 236 mm.

GPz B1 twin shock model. Front disc = 236 mm, rear disc = 236 mm

GPz B2 twin shock model. Front disc = 246 mm, rear disc = 236 mm

Z1000J. Front disc =236 mm, rear disc =236 mm

GPz 1100A1-3. Front disc =246 mm, rear disc =236 mm.

However, the unitrack discs look different in design/style to the B2 ones. Worth a closer look to see if the mountings are the same though.

83 on GPz1100 brake disks are larger in diameter than 83-85 NA GPz750 brake disks, and 84-85 GPz750 Turbo are larger in diameter than 83-85 NA GPz750 brake disks.

I don't know if the Turbo brake disks are the same size as the GPz1100 though.

Hi, I also found some information that said that the Gpz1100 have 280 mm diameter for the front discs and the Gpz750A1 has 270 mm.

So I guess the disc from a Gpz1100 won´t fit my Gpz750.

Thanks for your help!
