The winning weapon.
It looks like it is moving even when it stands still. It has a streamline, feisty profile, with its aerodynamic cockpit, and streamline, nimble tail. The gold-coloured forks aim towards the road, almost embracing the front disks where the powerful radial calipers stand out. The impression of power and elegance is emphasised even more by its performance. The air-cooled 1125 cc V 90 degree two-cylinder, four-stroke, four-valve engine pushes forward at all speeds. All it takes is a look at the components to understand why.
