    Completely different piston, highly likely won't fit.
    If you can't get the wemoto part, try AJP

    I installed the wemoto piston kit. Still get some air in, but that's because the bore of my clutch master is too far gone, scratched. The wemoto seal and piston aren't falling apart, so it's probably good.

    Thank you, Yzf.
    I ended up attempting to bleed the master through the banjo a second time before I tore into the master and it worked. I didn't think it was bleeding but results from searching the forum reminded me to bleed it thoroughly. This forum is awesome. Thank you, guys.

    After chasing seals for my Futura "Brembo" Master cylinder I can confirm the following part numbers.

    The actual dimensions of the Master piston/bore it is to fit is 12mm od x 7mm id x 4mm SU12-7-4-EP-DS106 IS CORRECT


    The actual dimensions of the Master piston/bore it is to fit is 12mm od x 5mm id x 4mm SU12-5-4-EP-DS106 IS CORRECT

    The actual dimensions of the Slave piston/bore it is to fit is 28mm od x 20mm id x 4mm wide SU28-20-4-EPDM-DS106 IS CORRECT

    The suppler is FPE Seals Ltd, 7 Barrington Way, Darlington, County Durham, DL1 4WF, England.

    The staff are extremely helpful.

    Sorry I have obviously confirmed that the wemoto part (https://www.wemoto.com/parts/picture/is-brembo11-9) fits the falco in the wrong thread. It was also a better fit than the part from FPE seals that I have also tried.

    The seal from FPE seals was a little too big and the lever did not return easily so i went back to the original seal that had a bit of life still in it.

    Then i got the kit from wemoto on yzf600r s recommendation and it fits much better. It is described as 11.9 mm, but i am afraid at the time I did not know the FPE seal was 12 mm or that there could be some discussion about what the correct size would be so didn't think to check the difference in sizes.

    The wemoto part worked better for me though, and is still functioning about 4000 km later.

    Best of luck to anyone who needs the seal

    Tim

    As luck would have it, I now need to replace the Master Clutch Seals as well, 20 years and 37k miles.....been leaking a long time, and finding a gear or neutral is getting harder and harder.

    So, anybody in the US found a North American Supplier???

    gr

    **The wemoto link mentions that the "rebuild" kit services BOTH Clutch and Brake Masters (at the lever).

    Can anyone confirm this?? I happen to have a spare OEM Brake master that might get cannibalized if so!

    It's not the years, it's the MILEAGE!
