Called the Superquadro Mono, the 659cc motor is claimed to be the highest revving and most powerful road-going single-cylinder ever produced, kicking out a claimed 76.4bhp in standard spec and an impressive 83.4bhp in track-ready form.
It’s also capable of engine speeds previously unimaginable for a non-race mono, revving up to 10,250rpm – courtesy of a desmodromic top end.
