Minnesota-based Aerostich is well known for its line of cold-weather riding gear, and their Arctic Grip Heaters are perfect for riders looking to stretch the season as far as possible. A pair of wafer-thin heating elements that install between the handlebar and the grips, the right and left heaters are calibrated differently for maximum heat control, with no throttle-side resistor needed to equalize temperature. The grips come with everything for installation including a 3-position hi/low/off switch. For 12-volt systems. $47.
