Sir, that is impressive.

I used ti ride year round, but I don't have the gear for it anymore
Nor the stones  

One other issue might be.....the Suzuki Savage only has about 100 watts of generating power for the lights, ignition, and battery charging.  Since you only ride 12 miles, and may be doing that with the heated gloves on when really cold...you might be running the battery down a bit.  Also batteries lose a lot of capacity when really cold.

However...you did say that jumping the bike from a car still did not allow the starter to work, and that would indicate the problem was not battery related.  Next time you need to jump it and it just clicks, you can turn the bike on, and then run the jumper cable directly to the positive terminal on the starter and see if it starts.  I needed to jump my bike from a car once, and you cannot get to the tiny battery terminals easily....so I turned the key on, attached the jumper cable to the positive terminal of the starter and the negative cable to the engine case where the negative terminal attaches, and I held them in place.  I then I had the other fellow attach the cables to his car battery to run the starter.....and I had him pull the cable off his battery as soon as he heard the engine start.

Do you have any friends that work at a frozen food plant and will let you park the winter/beater bike in their freezer for some cold weather testing?  I worked at a distributor for frozen food when I was in high school loading trucks in the morning before I went to school, and the freezers were at -5!!!!!!!
