ABSTRACT:
A grip heater has a tubular insulator that is designed to slip over a handlebar and has two interposed pairs of helical recesses. Each pair of helical recesses is formed by two parallel helical grooves and accommodates a heating element; the heating elements can have different resistances to provide differing degrees of heat when selectively connected to a voltage source. Preferably, the pairs of recesses overlap such that the heating elements reside in alternating grooves and cross over each other. The heating elements can be connected to a common ground to allow replacement of existing three-wire grip heaters. When a common ground is employed, the heating elements are preferably isolated where they cross.
