    Default 1978 1000c

    Iím looking to buy front brake caliper 59300-45022/calipers-assy for my 78 1000C. How can I tell if it is for a single disc (C), and not for the twin disc (E). Are there any special markings or stamped part numbers.
    thanks

    Yes I am aware that there are different part numbers for the e/c. What I am asking is there any way of telling which is which by looking at them.

    Well, if you have 2 to compare, the single disc caliper has a much bigger piston
