ON THE COVER
Ducati’s new Superleggera V4 is the world’s only street-legal
motorcycle using carbon composites for its entire load-bearing
chassis structure — frame, subframe, swingarm and wheels. The CF
components are 100% tested using aerospace-spec thermography,
ultrasound inspections and tomography. The svelte machine boasts
a 1.41 hp/kg power-to-weight ratio. (Ducati photo)
