A pipe and slippers are to BMW what Werther's Originals are to your Grandma. At least that's the old stereotype that the German company is now desperately trying to reverse. Witness the BMW F800R Chris Pfeiffer, a replica of the factory-sponsored stunt rider's own machine. Little more than cosmetic modifications -- red, white and blue paint; stickers; flyscreen delete; LED indicators; a white front wheel; a red spring on the shock; an Akropovic exhaust and Pfeiffer's signature under the clearcoat --it nevertheless draws a clear lineage between between the world of stunt riding and BMW's showroom. At least to European showrooms, the BMW F800R isn't available in America.
