There were some cool ideas on those bikes. There were three, if I recall correctly.
V12X supermoto
V12 Strada standard
V12LM sporty bike
The frame is a monocoque. In the show bikes it was plastic, but could've made from aluminum for production, I suppose.
The tanks and bodywork had nice organic lines. I like them much better than the angular mechanical bug styling so common on motorcycles today.
Funny, Terblanche left Piaggio in 2010, and Galluzzi became cemented into the Guzzi styling department.
And these concepts died quietly.
