Every detail was designed for a "crossover" use of the motorcycle: choice materials for the layers of the shell, extra comfortable high-tech fabrics for the interior, internal VPS sunscreen, standard ready for the N-Com® X-Series communication system. Its streamlined but "muscular" lines are made even more attractive by the visor (perfectly combined with product design), the large peak & the complete & practical ventilation system.
