The new Hollow Symmetrical Swingarm perfectly blends form and function. A complex, sophisticated and elegant structure, it stands out among sports bikes for being coupled with an exhaust positioned under the engine. The swingarm has lateral arms with a significantly lighter design and large slots on the sides, which optimise the external structure to satisfy pre-determined weight and stiffness requirements. To maximise efficiency, the internal structure has also been hollowed out and lightened, creating a complex system of cavities and openings, some of which are closed off to the outside with aesthetic elements in plastic material.
