Keep comfortable on those cool morning or frigid night rides. Warm hands have a major impact on overall body comfort, and sometimes gloves just aren�t enough. These thermostatically controlled grips have variable heat settings and automatic temperature monitoring to adjust to changing ambient temperatures. The grips remain at a constant temperature regardless of changes in outside temperatures. The self-contained control circuit and control knob means you have no additional switches or controller boxes to mount, and the grips are switched on/off with the ignition to avoid draining your battery. The �glueless� grip design allows grip removal if you change handlebars or motorcycles. Patent pending.
