Autoblog visits the San Diego Auto Museum, Part II - The Bikes

Today we continue our photographic tour of the San Diego Auto Museum. Despite the fact that the building is dedicated to four-wheelers, there are actually more motorcycles there than cars. That's alright with us, as the bikes on display are some of the coolest machines that history has to offer. Starting with some of the earliest cycles powered by rudimentary engines, it's easy to see just how far we've come in just about one-hundred years or so of mass production. Take a gander at some of the first motocross bikes, land speed record racers, rotary-powered cycles, modern choppers and scooters (including one from Harley-Davidson) in our gallery below. Our personal fave? That would be the 1951 Vincent Black Shadow.
