Well if we're really talking wanting to be warm you should go for a heated vest over grips or gloves because it sends out warm blood to your extremities. ;)

But I think the grips are much better since you can wear whatever gloves you want AND heated gloves are cumbersome.

My hands are the only thing that gets cold. Wearing a heated vest wont help me if I'm already warm. I'll just be hot. Your heart will only pump as much blood as it's told to at a specific rate. I have less than stellar blood flow in my hands and my arteries aren't that big.

Apparently I'm not the only one who can't read...

have you considered glove liners? They are cheap and actually do a very good job of keeping your hands warm.

Heated grips are okay... But they only work as well as you can keep the wind off your hands. Down through about 35 degrees, heated grips and insulated gloves are great. Below that, I've tried insulated leather gloves, uninsulated leather gloves with the silk/wool/UA liners, and either combination with grip heaters. After a while, the cold wind always bleeds through. Those battery powered liners look great (and reasonably priced at $50), since I DO NOT want to be wired to my bike.

Gerbings does have some battery powered gear, but it's not meant for riding- it doesn't have as many heating elements. If you had the right battery pack though, you could run their moto-specific stuff without wiring to the bike.

I'm in the same boat that you are. I rode to work the past two days with the temps in the high 20's, and after 30 minutes, the tips of my fingers were numb. I spoke with a dealer who rides year round, and his preference was heated grips. I think I'm gonna buy a pair just to see how they do. I hate the idea of heated gloves being attached to the bike. I'm so scatter brained, I would rip the cord out the first time I used them.

That is unless I can find out where Tigger got the hand warmers in his pic. I don't know how they would look on the bike, but I'm willing to try :tremble:

Personally I think electric gloves would be stupid. They wouldn't have enough "feel" as regular race gloves, and they'd have a wire hooked up to them. Nobody I know uses them. Heated grips are enough. The back of your hands don't get all that cold, that part of the glove always has more protection anyway.

I have heated grips on 3 of my bikes. As noted even with insulated gloves at 30 or below the backs of your hands get cold. The upside particularly here in New England where we have WIDE temp swings through the course of the day is that the heated grips are always on the bike. Nothing extra to carry or plug in. So if I ride starts in the morning before sunrise you can wear a light pair of gloves and a low setting you are good later in the day you shut the grips off and no extra baggage. If a trips stretches into the evening and it gets cool or cold again turn them on and it is great.
I would recommend the Oxford product. Their base package has 5 settings for heat. I installed those on the B King. I have Hot Grips ($69) on the Busa they have a Hi Lo and off. That translates to not quite enough or Damn that is hot. So when I ride that bike I wind up switching back and forth not really a problem and for another $39 they will sell you a variable controller. Vs The Oxford Grip Package (not the wrap) which was $70 for the package.
Again for me because I am a bit lazy and don't want to carry a bunch of extra gear the heated grips are the right choice.
I am also considering for the B King http://cozywinters.com/shop/heated-motorcycle-seat.html
Say what you want the heated seat makes all the difference on the Goldwing

Yea that's why I always used silk liners and they are get super small when it warms up during the day... To be honest, I LOVE to ride but as I've gotten older, I've decided that there is such a thing as "quality" of ride and I'm not feeling it when I have to be terrified of every shimmer on the road and I'm bundled up, barely able to move freely... Of course, that's just me but I can always ride another day if it's below about 50 degrees...

new first gear thermaflex gloves are good to about 45

heated grips with above gloves are good to about 35-40

moose racing paw gauntlets with above are good well below 25, I haven't taken the bike out below that because my other gear gets a lot colder first

Hell, I used race gloves with nothing else for plenty of 35-40 degree rides to work........Is it optimal, no, but I don't see the big deal unless you're riding longer than half an hour. If you are, then just add some grip warmers. Fuck thick gloves, they suck.
