    ...The aftermarket rotors are marked "BRAKING", so I guess Sunstar brand?...
    "Braking" is an aftermarket brand by itself as is EBC or Ferodo; it is not a Sunstar "branch" or division.

    ...When I changed out the p)ads to EBC HH ones, on the old pads I noticed that there was a small portion of the pads not subject to any wear. It seems the aftermarket rotor diameter is slightly (a guess would be 5mm) less than what they should be. I figure the the tips of the petal features on the rotors' edges catching the radius of the un-worn pads area, are the cause of the aforementioned flutter sensation...

    This is not normal. Any aftermarket rotor is made to fully cover the area the pad touches on OEM rotor. My guess is that the rotors on your bike are not for a Versys 1000 but for another bike that is using 10 mm (diameter so 5 mm radius) smaller units. Personnally, I would change those rotors asap.

    When I open the BRAKING brand's own website,

    I only see SUNSTAR, not EBC or Ferodo...

    Agree, but I'll just mod (or continue to use as-is) the pads to clear the problem. The amount of un-swept area, is very negligible when compared to the current swept area. Not sure if I'd even be able to perceive a difference, if I'd spend hundreds of dollars for a new set of rotors. The BRAKING ones on the bike are fine. I never had any real issues with them, or with the performance of the OEM (assumed) pads that were on it when I bought the bike. The EBC HH pads are an upgrade in performance over the previous though. Have gone through a few sets n my Gen 1 FZ1, and have always liked them.

    My apologies then... I already bought "Braking" rotors (decades ago) for a previous bike and I never saw the Sunstar name or logo on them so I assumed it was a brand on its own. Maybe Sunstar bought the company by after? Anyway, should have Googled it; sorry.

    Not quite sure how this dovetails into semi floating or full floating but there is no need for brake discs to rattle. If seen plenty with spring washers.

    So I know this is an old thread but just wondering if other are having issues with pulsing front brakes. Mine were doing it and seemed to be resolved after a visit to Kawasaki, however after a long ride in lots of rain, shitty dirty roads for hundreds of KM's the surging has returned with a squealing under light breaking. Last time Kawasaki said the semi floating was stuck and the "buttons" has seized making the disc not parallel, this then glazes part of the disc with light breaking pressure in an area. Really annoying and just wondering if im the only one having these kind of issues.

    I do that every so often, but with a spiral bolt extraction tool. CCW grabs it and spins, CW quick release.
    I'm lazy. There are too many of them for a bolt and nut.  :151:
