Actually Noland...Yes, that is supposedly the BMW Inline 6 sportbike. That set of three exhaust pipes is supposedly on both sides. Google, Images: "BMW inline 6 sportbike" and that bike will pop everywhere with the pipes showing up on each side. You never see both sides at the same time, so I'm not sure if it was photoshopped to whichever side was shown, or truely both sides.
Looks cool, but not sure it was ever real. It may have just been added to the concept bike Sockmonkey is talking about. I kind of seem to remember both, but I know I remember this bike being related to the I-6.
