Speaking of counter weights and whatnot...

Here's something i have never seen in the car world.

The 1993-1995 Ducati Supermono used a "dummy connecting rod" that acted as a second piston. It overcame vibration from the horizontally placed 550cc Single cylinder.



I saw the bike in person in Italy *thats my picture*

Pierre Terblanche best ever design in my opionion.
