It was about -15°F at my house this morning from neighbor's accounts, I wasn't up that early, but at 9:30am, after the sun had been on my thermometer a couple hours, it was up to -5°F, by noon time, it climbed to +10°F and I said by gosh, I'm going for a ride it’s a sunny day. With heated grips, hand guards & electric vest, I was toasty warm, till I stopped for gas, my winter gloves are too thick to fumble with the key, credit card in wallet etc, so I ended up having to take my gloves off, which led to grabbing that cold metal gas pump handle, also the swipe at the pay at the pump didn't take so I had to unplug my electric vest, and I was inside in line so long that my heated grips cooled off(a bunch of snowmobilers pulled in at the same time as me) but at least the ride home from the gas station was only 3 miles the cold hands were well worth the enjoyment of getting the "wave" from a whole lot of bikers that are in their cages or on snowmobiles for about an hour & half (60miles±) And the crisp throttle response you get with cold dense air.
TIPS:
Keep speeds to less than 60-65mph above that and wind chill blasts right thru a motorcycle helmet even wearing a balaclava. And; Make sure your balaclava covers every part of your face that may come in direct contact with your helmet (especially the breath deflector) ever stick your tongue on bare steel at -25°, when you take your helmet off, so it slowly, breath heavy in your closed shield helmet and allow anything sticking to thaw, don't ask how I know.
