Heated grips are cool but I wonder if they're necessary if your hands are covered while you're riding?
If you wear a warmer glove and the airflow to the hands is blocked, shouldn't the hands be fine? It's the air running over your hands that will cool them and if that is eliminated, as it is with certain windshields, I'd think you wouldn't have to worry about warming the hands...
I don't ride the bike below 45 degrees anyway...I guess if you enjoy riding around the freezing level...:dontknow: But, that isn't very enjoyable anyway....better to get out the snowmobile!
