Guardian (Gremlin) Bells are a long-standing biker tradition believed to protect riders from bad luck and road �gremlins.� The bell�s ring is said to trap and shake out these troublesome spirits, keeping the bike running smoother and the rider safer�especially when the bell is given as a gift. This solid metal skull bell is a universal fit for any motorcycle, ideal for Harley-Davidson, cruisers and customs. The included chain is for display only and must be removed before mounting; secure the bell using a cable tie or metal ring to the lower frame or foot-peg bracket for best results.
