Built in the year 2000 by Franz Langer, the motorcycle is based on an NSU Konsul and uses a radial aircraft engine cylinder to increase the capacity to some 2000cc. This was done in order to regain his Guiness record for the world's largest single which he held previously for a 1000cc machine, and then briefly lost it to one of 1400cc.
