con: cages only prtect the mid fairings and the belly pan. no protection for the gas tank, subframe, clip-ons, clutch/brake levers, windshield, front fairing/headlight or the rider.

you are going to face the facts if you own a bike and plan on riding it, theres always the possibility that you are going to crash and theres no guarantee that you will save the bike no matter if you have frame sliders or a cage on it

most commonly, stunters have cages.

also, whats the chances that the bike goes sliding down the road/dirt the wrong way and the cage digs in just the right way and cases your bike to flip end oaver end???

remember anything is possible with a bike, once you're off its out of your hands
