Uwe Oltmann made a 5-cylinder Puch, it’s unrideable. It runs with all five cylinders firing enthusiastically, but once you get it going, it’s far too noisy and hot to be usable.

This project started as a 1976 Puch Maxi S moped, to which Uwe promptly added four more Puch engines. Each engine has been bored out to 70 cc, with a central shaft linking the bottom three engines, and two belt drives connecting the fourth and fifth.

This moped also features a prototype swingarm and a set of race-spec WP Suspension, both from Ralf Waldmann’s 1993 Aprilia RS 125 R Grand Prix racer. The front wheel uses a heavily modified moped rim, the rear wheel is a magnesium item from PVM

The start sequence includes spinning the rear wheel to get the first engine going, then releasing each subsequent engine’s fly clutch with a wrench. The 350 cc Puch makes 127.5 decibels at full tilt, and the only way to stop it is to pull all five spark plugs.

Skip 2 minutes 25 seconds to get to the start up:

Because it can be done, and ought to be admired for the utter goofyness
