The bar mounts don't fit well at all on Pro Taper Evo's. The cutout is too small of a diameter. I pulled some mounts off another bike with Pro Tapers and Moose handguards to make sure I wasn't crazy and indeed the Moose have a bigger cutout and better fit (and I wasn't that impressed with the fit of the Moose when I put them on years ago). Had to take a Dremel tool to grind the cutout. It fits now but will probably twist easy since I couldn't do a smooth grind and it won't have as much surface area to clamp with. If you cut your bars down you will really have problems. I realize these are probably made in China but come on guys how difficult can it be to make mounts for one model of handlebar?
