I guess it's an engine of a Harley Davidson, though I'm not totally sure.
TECH-INFO: lots of trying, zooming, walking closer and further to get a great frame. I wanted to have good composition. There is not much depth so an aperture of f/8 yields maximum sharpness for my lens (24-120mm f/4 Nikkor).
In LR4 I converted it into B/W and enhanced the contrasts.
