Up another stairwell thousands of boots, chaps, windbreakers, pants, leather vests, saddlebags and many, many key rings (stamped with American symbols such as the Union 76 logo) greet you. On the fourth floor, the apparel is dedicated to keeping you warm during a winter ride. And on the fifth, and last floor, finally you find the reason the place is called Racing D's Connection. The door to this floor is kept shut, and what lies beyond is the "other trade"—SP Tadao Racing Parts. As you enter this floor, two cartoonish eyes in the corner stare at you from the helmet of Shinya Nakano, the runner-up 250 Grand Prix rider. "Yes, we sponsor Shinya," proudly acknowledges a salesman, "but also [Naoki] Matsudo in 250 GP."
