Diesel Moto Guzzi?

This radical turbo-diesel Moto Guzzi is a concept by the Italian industrial designer Paolo De Guisti.

Styled to evoke memories of iconic Guzzi singles like the Falcone, the 903cc oil burner drives through a hydraulic transmission. It's De Guisti's dream to have a bike that will easily do 550 miles on a single tank, hence the choice of DERV as a fuel.

Sadly, for now, it's just a dream...
