New Moto Guzzi Door Mats Available Now
Much like departing the house in the rain, I just don't see the point. Maybe I'm insufficiently hardcore, but I think motorcycling is supposed to be enjoyable. I find riding in the cold to be uncomfortable and riding in the rain miserable.
To me, the main factor is likelihood of ice. I can deal with cold temperatures, but ice spooks me.

An old friend had his "40-40 Rule." If the chance of rain was over 40% or the temperature was below 40 Fahrenheit he took the car. I rode a bit in sub-40s this year. A little goes a long way. Heated grips, glove covers, and Firstgear winter base layers (top and bottom) help a great deal.
