Motorcycle engines can be a thing of beauty. In many cases their beauty cannot be fully seen since there are other beautiful elements close by in the motorcycle that distract from the engine itself. Gordon Calder takes care of that with his collection of photoshopped motorcycle engines. He removes the background so the engine's full beauty can be appreciated. He accepts pictures sent by people, it would be nice if someone could get him an Interceptor engine picture. And how about a 1930's KX V-Twin? (Hat Tip The Kneeslider).
