I've seen those Corey. Thanks for the reply. I was trying to come up with some way of still using my CRG bar end mirror with the Renthal clip-on's for when I ride the street.You don't need thread to put bar ends in them. Nearly all aftermarket clipons don't have thread. You use universal bar ends like the suzuki's have that expand in the bar. Such as Driven bar ends. Anything that has rubber on the end that goes in the bar and then when you turn the bar end the rubber is squished and expands will work on those. Same as woodcraft, driven, vortex clipons and nearly all other aftermarket clipons.
