Griso 8V SE

Griso 8V SE has impeccable style; this machine is an instinctive creation, pure, solid and distinctive and in many ways a work of art.   The design details are discreet but elegant and pure quality; the lines blend together and are accentuated by the chrome finishing and satin metal.  The fuel tank lends itself superbly to the strong frame creating an aerodynamic teardrop body which is continued through to the tail which houses three high intensity LED light units.

The Griso is decidedly masculine and powerful yet the “Quattrovalvole” engine seems to be set like a jewel in a frame that shows off its revolutionary design to the utmost effect.  Returning to the performance, it becomes obvious that the sophisticated components are not mere technical details included for the sake of style but enhances performance and provides guaranteed reactivity.
