For riding comfort on cool mornings and frigid nights the Airflow Heated Hand Grips (P/N 56100107, $269.95) offer thermostatic control of variable heat settings and adjust to ambient temperatures. The self-contained control circuit and control knob means there are no additional switches or controller boxes to mount, and the grips are switched on/off with the ignition to avoid draining the motorcycle battery. The Airflow design combines a traction-grip crosshatch rubber surface with a comfortable 1.6-inch diameter for excellent control in wet or dry weather. These grips fit 2016-later Dyna Low Rider S and Softail and 2008-later Touring and Trike models. See an authorized Harley-Davidson dealer for fitment details.
