Hi, I have a 1980 KZ 750 LTD. I have purchased two sissy bars/ luggage racks on eBay and sent them back loosing money each time. I can't seem to get a sissy bar that fits my bike. Does anyone know if Honda CB's are the same size? Should I search for backrests in their models or Suzuki GS's? Any tips? I really want one and their aren't any for sale in the exact year and model of my KZ.
