Thread: Cast iron top triple clamp

  1. #1

    Default Cast iron top triple clamp

    What years did Harley use the cast iron triple clamp on the Sportster?

    I have one that has 4 "ears" on the top and my parts books don't show that little detail in the exploded view diagrams. I did find a page that shows it as a "ghost" image in with the handlebars, but that doesn't help me identify what it was used on.

    I will post a picture of it once I figure out how to post it on this thread.

    The one with ears is a type used on '52 to '56 K Models or a '57-'58 Sportsters. There are a couple differences in those also so pictures are needed especially around the stem area. The ears hold mounts for the ignition and light switches.

    Thanks for taking the time for this. I hope that I do this right. This is what I am trying to identify. It has been welded, machined, polished, and chrome plated. It was on the front end on my 53 Fl when I bought it in 1980. A mild chopper from the late 60's that I just had to have back then. Now I am continuing the restoration process

    Is this version with the 4 tabs correct for all 57 58 models?

    That is what I found out in my old parts books. Late 1954 to 1956 KH and 1957 & 58 Sportster for the part I have.
