well, today for example - 65 and sunny during the day. I ran around town on my Panigale with normal leather gauntlet gloves. but I had client appointments that ran into the evening, where the temps dropped into the mid-50s. I switched to the Multistrada, where with the heated grips I can actually use summer gloves.
What sucks is that if the Panigale also had heated grips, I probably would have stayed on that bike. I may add an aftermarket option, although I'd really prefer not to mess with the stock grips, which I like very much.
I can't be bothered with batteries, wires, so heated gloves are something I've never considered. So it's regular insulated gloves for me. And when I need practical/durable, I move away from the pretty Dainese stuff and go with boring BMW.
They work, until you soak the insides with perspiration. Then they get very, very cold. So the trick is to carry a bunch of latex gloves. The gloves keep your hands warm in two ways - as a vapor barrier liner, and by keeping the insulation inside the gloves perfectly dry. The latex gloves need to be changed at every stop, so like 1-2 hours. They're a lot bulkier than normal gloves, but not overly so - it takes a bit of practice to not have your fingers trip over the levers, but once you're comfortable with these gloves, they will work to extremely cold temperatures without needing heated grips.
But PLEASE DUCATI give us optional heated grips for our 1299s!!!!
