One ball with assorted mounting hardware is supplied with each mirror purchased. Please view the 7th image over for a list of bike fitments. Adventure: 5.5" Wide - Best FOV Perfect on bikes like KTM LC8 & 790/890/901 Most Stable Enduro: 4" Wide - Good FOV Perfect on bikes like KTM EXC Best Folding If you're deciding between the Adventure model, and the Enduro, our advice is simple. If you plan to fold the mirror down a large percentage of the time, the Enduro is right for you. The long size means the head of the mirror tucks away right behind the headlight. If the mirror will more or less remain extended, get the Adventure- the more compact design is more stable at highway speeds. Either way, you can't go wrong IF YOU ALREADY OWN DOUBLE TAKE MIRRORS YOU CAN UPDATE TO THE NEW MOUNTING SYSTEM BY FOLLOWING THIS LINK TO OUR SPARE PARTS PAGE
