I have used Widder heated gloves with my last 3 Goldwings over the past 20 years and thought they were great, until I got the Harley with heated grips.
I can now wear my summer gloves and have the grips on 1 and my hands stay nice and warm.
I live in Tonopah and have used my heated grips and like the heat(didn't think I would) but I do think the factory grips are ugly. I wished Kuryakyn would make the ISO grips in a heated version.
Harley makes a variety of heated grips if you don't mind paying the price...somewhere around $250.00 for anything other than stock which are $199.00.
