Bought some $16 bar end mirrors off Amazon to try.Found out the Like handlebars have a threaded bung inside them after I took the end weights off. The mirrors I bought bolted right into these threaded bungs after I took off the expanding plugs that came with the mirrors. I'm a big guy and can easily see around myself now. I love bar end mirrors, having used them on airhead BMW's for years. I may buy some better ones now that I see how easy they are to install. But, these are working good for now. They do add to the width however, about 6 inches total.
