    Or are there any other FZR models that would work?

    Also any recommendations for a good quality brand? I bought a cheap one and it warped!

    Thanks

    2KR uses a single, larger diameter disc

    buy from metalgear or bk performance. overseas crap is cheap for a reason.chinesium steel is recycled waste so you get what you pay for.

    I found this website that lists a number of Yamaha models that seem to use the same rotor as the 2KR:

    https://japan.webike.net/products/fit-model/22897628.html#YAMAHA

    The dimensions of the rotor are:

    [Outer diameter] 320
    [Inner diameter] 64.0
    [Thickness] 5.0
    [Number of bolts] 6
    [Bolt diameter] 8.5
    [T / H] 10.00
    [PCD] 80.0

    If this is true there are a lot more options than just searching for FZR250 2KR rotors including this Brembo:

    https://www.ebay.com.au/itm/401636040180

    Does this seem like it would work?

    That disc will work. Best quality out there... and not cheap :)

    Great thanks for confirming. The Brembo is only $15 more than the Metal Gear so I'll give that one a go.

    OK just a quick follow up to confirm that the Brembo rotor fits. The reason the previous rotor warped was because a previous owner had stripped one of the caliper mounting hole threads and put in a Helicoil to fix it but it wasn’t wound all the way in so the caliper and rotor weren’t aligned properly! Ended up replacing the caliper as well with one from an FZR1000 which fits and uses the same pads.
