The other morning rode my tiger to the dealer near me. It felt warm so i didn't bother wearing my balaclava (mistake). I thought the bottom of my chin was going to get frostbite before I could get there. On the plus side it did feel a little ivigorating. Anyway, What's the coldest weather you've ever ridden in?
Mid 20's but that ice and frost on the roads is not good.
Above freezing no problem.
The key is to dress for it, in layers. If you're too warm you can always take off a layer. Once you start shivering, it's ballgame over.
Ride safe.
I used to teach in a prison system. A lot of the guards didn't like teachers coming in to teach. Lot's of threats and harassment, ..., 'til late fall, and the temps dropped into the 20's (Fahrenheit). They thought I was local and a little nuts. Then they learned I rode 70+ miles each way, and were convinced I was very nuts. No more threats, and a lot more respect (at least a comfortable distance).
How far? Anywhere from a 10mile blast to kill cabin fever to 200 miles riding the backroads. It just depends on what I have to do. Silverado57 is right, dress is the key. I really don't mind cold as long as I can dress for it. My son lives 100 miles from me and I visit him regularly year round on the bike.
