A motorcycle may begin as a drawing, but its shape eventually has to meet the demands of construction. Ducati Style Centre designer Jérémy Faraud, who worked on the Streetfighter V4, describes a process that starts with artistic freedom and gradually takes in engineering reality. The initial sketch can explore a character; the finished design must also fit the mechanics, the rider and the way the machine will be made.
Faraud gives particular weight to the front of the motorcycle and its fuel tank. He sees the front as the part that communicates a bike's expression, while the tank helps establish the attitude of its whole silhouette, even at rest. Those lines are more than decoration. Their effect depends on how convincingly they sit alongside the riding position and the parts beneath the surface.
An idea that cannot be built today may become possible with different technology, he suggests, so an early sketch still has value even when it challenges practical limits. Yet a production motorcycle needs more than a striking outline. Good design holds on to its character after the engineering questions arrive and remains understandable to the person who will ride it.
