Even after a whole life of riding and racing I made a complete newb mistake when I picked up my new Busa at the dealer. Drove it off the lot and did about 147miles on it that day. It all seemed right, but it cornered like a pig, would want to stand up in any low speed corner, way too much bar pressure to keep it down when it did finally fall into a corner...next day checked my tires...21lbs down on the front and 14 down on the rear. They just pulled it off the showroom floor and handed it to me...Duooh!
