Originally they were to protect the bar ends and grips especially the throttle tube. Later many added weight to absorb some of the vibrations. We now have them with helmet locks incorporated. Your choice as to weather you want them or not. Chances are you will never have the problems for which they were intended as it is hard to drop a spyder....:roflblack:
