Automotive Designers on LSD, this is Honda NR750. oval pistons, yes anything can be done,.. but why. Even I can come up with crazy engineering concepts,... like keep the piston stationary and reciprocate the block,... er der!.
While the engine comes from a Honda Bol d´or 900, pretty much everything else was custom made by Bavarian outfit Custom Wolf. Some of the detils on this bike are truly amazing and certainly inspirational. A lot more pics here
