Legend has it that a small bell attached to your motorcycle, close to the grand, catches the Evil Road Spirits. The Little Gremlins live on your motorcycle causing all kings of mechanical problems.
The cavity of the bell attracts these Evil Spirits, but the constant ringing drives them insane and they lose their grip and fall to ground. ( Have you ever wondered where pot holes come from?)
A Guardian Bell carries twice as much luck when it is purchased by a friend or loved one and given as a gift.
