Every year the letters and e-mails sing the same tunes: "You Californians don't know how lucky you are getting to ride all year. I have to wait another three months before I can ride again." Or our personal favorite, "The temperature got up into the 40s today, and I just had to go out for a ride. Although I may never thaw, I needed to spend some time with my bike." Well, devoted cruiser enthusiasts, never fear, you can spend quality time with your motorcycle, without risking frostbite -- in the comfort of your own garage. Winter is the perfect time to perform some essential maintenance so that when spring rolls around, you can spend your time riding instead of wrenching.
