I have rear brake update Zuki rep. called back Â and stated no knowledge of problem but a replacement rotor was on it"s way. The guys at my shop took care of me the way I hoped and Zuki is standing Â by their product.
I was surprised Suzuki used a floater on the rear. most all sport bikes use them on the front but you rarely see one on the rear. looks like the supplier of the rotor used some weak spring washers that go under the buttons on the rotor.
I was told the original design on the brake system was off the GSX-R series and the 200lb weight difference could be the reason we have the issue, as long as they back the product with the support some of us have had the rest should feel good about buying Suzuki.
Got mine replaced two weeks ago. Had to wait a couple of weeks after I noticed the problem because parts were on back order. I was told Suzuki pulled all of the old stock and were waiting for new ones to correct the problem. I have been about 500 miles on the new one with no problems.
