When out riding you want to make sure that you are seen by other riders. Mounting a flag to your machine gives other riders knowledge that you are on the dune hill, on the track or trail. Flags come in all different styles and designs. So get out and ride and have some fun, but make sure that you have the right tools like your flag. -2 inch - Fits Can-Am Commander and other machines with a 2 inch O.D. roll bar.
