So maybe you own a bike — even a couple — and if you're lucky, you might have yourself a small collection of bikes. But odds are, you'll never own a complete collection of the 100 most-desired bikes of the last 100 or so years. That said, you can at least ogle them in book form with the Impossible Collection of Motorcycles: The 100 Most Coveted Motorcycles of the Twentieth Century ($600). It covers everything from the 1903 Harley-Davidson Serial #1 to the 1999 Honda NSR500 GP, with gorgeous photographs and information on each model. While it may not be as good as riding the real things, it's a pretty decent place to start.
