The point I was making had to do with "most of us" not driving a cycle below freezing like we would a car. Because I often start my car in winter with the temps between -10F to -40F... I want the biggest battery available (and a block heater). I would never expect the battery in my bike to start it with temps like that. Several years ago in January, I pulled the bike out of the shed with the temps around -10F to trailer it south. The engine would barely turn over. My car had no problem. I had to put a tarp over the bike and a heater for an hour to loosen it up then vroom. My car with a 2.0 litre engine had an 800 CCA battery in it. My bike with a 2.3 litre engine only has 310 CCA. Thats a big diff in starting capacity for similar sized engines... Our little cycle batteries usually don't have to contend with the cold and neither will I if I don't have to.
