What is the typical impact of cold weather on a motorcycle and its rider in Massachusetts?

1. No effect — bikes work the same in any temperature
2. Tires take longer to warm up and grip less when cold, the rider's reflexes slow if chilled, and visors can fog — dress for the temperature and warm tires gradually
3. The engine produces more power in cold weather so you can corner harder
4. Cold weather improves traction at all speeds
