I can't remember now but I ordered it to fit my bike with the stock handle bars and it did, hold on I will measure right now.Yes the hardware did fit my 1 " handlebars. I bought the fairing off Amazon but not from National Cycle, I bought it from some place else that was cheaper, can't remember who it was but if you search the National Cycle 3 fairing there it will come up with all the distributors and their prices. It was an easy bolt on installation.
