I did a forum search but didn't come up with anything. Has anyone tried heated overgrips instead of installing a new heated grip? I like the idea of not having to remove the stock grips, and the fact that I can easily take them off when not needed. I use muffs, and they're OK for making sure my hands don't freeze entirely, but if I have to take my hand out for any reason (adjust my helmet, scratch my neck, whatever) I lose any & all heat in my hands and I can't warm back up. (To the point that I've had to pull over before and hold on to the heated grips on my husband's bike for five minutes before we can continue the ride. My ability to get cold and stay cold is ridiculous.) Since heated gloves aren't an option for me, I need something that will generate some warmth. Doesn't have to be super-hot, just enough to supplement the muffs.
I don't have winter-weight gloves, so if I do get these, it'll be along with the high/low controller since it appears they get pretty hot otherwise.
