warm hands any way you want 'em
Warm hands? Gotta have 'em. Like most of you, we know about cold weather riding here in the mountains of NH. I have tried in the last 30 years about every method of keeping warm hands on the controls. Every method has its pros and cons.
Heated gloves? Had some Widder lectric gloves for years. Personally I don't care for them. They never got truly very warm and every time you suit up you have to fish wires out of your sleeves and plug in your gloves. Too much work for me and not warm enough on a NH December afternoon.
Heated grips? There's the very inexpensive heating elements, like Kimpex you install under any grip you like. They are cheap to buy and a little work to install. I think they work fine. They are better if you wire in a Heat Troller so you are not wasting any power you are not using and so you can dial in the exact level of warmth you want. Down side is you need to be very careful that nothing snags on the wires and rips 'em out. A neat install is essential.
Then there's the heated grips with the heating elements molded right in. They cost a hundred or more bucks or more and most of them work great. I have read the factory Suzuki heated grips are very poor performers but I can't say I know that for a fact. But with any heated grip you are stuck with whatever rubber density and pattern the grips come with. They may not be the most comfortable grips and you have to live with them year round. Since they cost a lot that could be a bummer.
Heated grips wraps...I think they are swell. They cost around seventy dollars, they are very quick to install, they get bloody hot and do it fast. They are removeable in warm weather and allow you to have whatever grips you want. Yes, they do make the grips fatter but it's never bothered me any. Currently, this solution makes the most sense for me.
Heaters aside, you can bundle up your hands too. There's a farkle called Hippo Hands that are big quilted, oversized mittens that cover your controls. You stick your hands in there and it helps a great deal. For extreme cold riding, maybe colder than you really ought to ride in, some combination of heaters and hippo hands are the hot setup, pun of course, intended.
There! That's my two cents on warm hands. Now get out there and ride.
