Not sure how cold I've taken the Triumph out in but have gone way down in temps on a couple other bikes.
Got the HD Softail Deluxe a year ago and have been having a lot of fun cruising around at the speed limit. I also got my first Gerbing's electric jacket liner. I've had electric grips on other bikes but got some of their leather gloves to plug into the sleeves of the jacket. Very nice! I've also been using their electric socks riding my studded tire KLR thru 4 Alaska winters. My feet have never felt so good!
So anyway, I was able to ride studless till Oct 29 this year, the day before our first real snowfall up here. The coldest it got down to was about 20f or -7c. I've had electric vests in the past but it was quite an experience riding down the road totally bathed in warmth. VERY nice. I keep track on a calendar when the last ride of the year is each year and I've gone as late as Nov 9th.
From the last studless ride 2012. It had dusted but roads were pretty dry EXCEPT for one intersection that got compacted into ice that had me a little worried on my way out of town.
Lovely evening ride out the Seward Hwy, a Designated Scenic Byway along Turnagain Arm a few miles south of Anchorage.
Now about that "coldest."
Well, riding studs on a dualsport takes me deep into the winter. I don't commute on the motorcycle in the winter but have fun taking it out on occasion for a fun little spin.
I've ridden colder but this is the coldest with a thermometer in the pic:
