    Front Rotor Swap

    Hi to all, I am interested in swapping the front O.E.M. brake rotors and calipers on my 1982 GSX1100S Katana for a set of floating slotted brake rotors and the calipers from a 1985 GS1150. I don't have a photo to show - sorry. I have used the "Search" here and it does not list this rotor/caliper swap.

    Does anyone know for sure if this is a straight swap for the rotors and calipers?



    Thank you in advance for your help, cheers.

    Not positive but I don't believe it is a direct swap,
    Salty Monk has a brake up grade using 900 Fireblade rotors and Kawasaki Calipers though . Use the search function it should come right up.

    80 GS 1000gt- most favorite ride love this bike

    If it isn't going to make it faster or safer it isn't worth doing

      Yes, I have read Salty Monk's post on the brake up grade. The upgrade involves a Fireblade rotor swap and also changing the calipers. I am wanting to keep it an all Suzi swap so I am hoping it is a bolt off- bolt on deal? Could I be that lucky?

      Cheers.

        Metalgear website is a good reference point - they give dimensions.

            Yes, the rotors from the later bike are a straight swap onto the 1100 Katana.

            Same internal diameter, bolt hole circumference and offset. The '84 GSX1100 is 275.5mm in diameter while the OEM Katana are 275mm. Not enough of a difference to be noticeable.

              Hi Postman Pat, thanks for confirming the rotors are a straight swap. I am still trying to find out if the oppossed piston calipers from the 84/85 GSX1100E (US - GS1150E) will bolt straight on to the Kat forks. With the rotors being the same working diameter I am thinking the calipers should have the same contact footprint. Now to find out if the bolt mounts are the same and if the caliper will clear the spokes.

              Cheers.
