    Some 1100's are 1074 and some 1075cm...Why?

    I was just wondering why I have seen some 1100's have the 1074cm on the cylinders and some stamped 1075cm.....
    My 80' 1100E says 1075.

    Just wondering if there is any difference or anything noteworthy about this small difference.

    As they both have the same bore and stroke, Suzuki made it easy to differentiate between the 2-valve and 4-valve cylinders.

        There are both 1074 and 1075 blocks for the 16 valve. Never new why.

          My 80 16 valve was stamped 1074 but it wasn't a 1074/1075 for long.

            Guess its just a case of Suzuki's " multiple model parts".
