To get started, simply visit _www.harley-davidson.com_, click on the "H-D1 Customization" tab and then "Start Building." You'll be directed to a menu with tabs for Style, Fit, Function and Performance, each with its own laundry list of parts to choose from. (If that's too much work, click on the Pre-Configured tab.) Naturally there are numerous paint schemes and metal finishes to choose from, but there are also various wheel styles, seating configurations, handlebars, foot controls, intakes, exhausts, etc. Each item you select is immediately, almost magically applied to the bike depicted on-screen, and you're free to un-do any of them to experiment with other options. Once your dream bike is "built," you can give it a name to save it and even display it as wallpaper on your computer or smart phone.
