When I bought my first new bike, GSXR600k3, the sales guy and I were going over the basics before i took off. He said ALWAYS let it warm up to at least 90 degrees. I always did, and still wait until the temp gauge moves a bit on the Busa. Im religous about it, even with my car and truck, I always let it warm a bit before i go. The question is am I just being paranoid? A friend wants to buy a coworkers bike, and he never lets it warm up before he rides. The price is about right and the bike is never ridden hard, should he buy it? Thanks guys.
