79 KZ650SR Brake rotors ???

Has anyone put 79 KZ650SR rotors on a 78 KZ650C2 as a upgrade ? Im looking at getting a set of front and a rear drilled rotors for my 78 650C2 and was wondering if they will fit with the stock calipers ? If anyone knows please let me know... Thanks Wayne

The front rotors should be no problem, but the rear may be a different spec as the caliper is different.

You could always drill yours if they still have some life in them. I had mine done years ago as I found my brakes su*#ed in the rain.

I may have a set from my '79 C3 (factory drilled) in my workshop. I know the rear is just about toast, worn to the minimum specs because of the Sintered Pads. I could check to see if I have the front 2 if your interested? I may have sold them, but I somewhat remember seeing them not long ago.

I just checked buy kawasaki, as I should of before asking this question, the front rotors are the same part number, but the rear is off by one number. rstnick please check your u2u. Thanks for the reply... Wayne

Here's a pic of the '79 C3 front rotors:

I put SR rotors on my 78 B1 and had trouble. I had to change the fork tubes as welll as the rotors were larger and the calipers wouldn't mate up properly. We originally thought they were the same size - but found out during the install they weren't.

The fronts bolt right on and work great. The rear will not work because the rotor is thicker than the C models. The SR uses a different rear caliper.
I did this conversion about 15 years ago on my 78 KZ650C1.
