We haven’t seen a good solid stirring of the motorcycle rumormill in a while, but today whispers of a BMW six-cylinder naked bike, a K1600R if you will, have be filtering through the web forums and into our ears. With the rumors centering mostly around the fact that BMW introduced its 1,600cc inline-six motor at EICMA in 2009 by sticking it in a very attractive street-naked motorcycle, speculation has begun as to whether the Bavarian firm would follow that concept up with an actual production model (we always did find it strange that the concept for a touring motorcycle was a street-naked).
