The Streetfighter V4 uses the "Front Frame" frame derived from the experience gained in MotoGP, which uses the Desmosedici Stradale engine with a load-bearing function.
The main difference in layout compared to traditional perimeter frames is the use of the engine as a structural element. The "Front Frame" provides a compact front structure, weighing only 4 kg, fixed directly to the upper half-casing of the front bank and to the head of the rear bank of the V4, whose base also acts as a fixing for the rear suspension and as a fulcrum point of the single-sided swingarm.
The most important advantage of the Ducati "Front Frame" is the use of the Desmosedici Stradale engine to achieve the desired stiffness: this has made it possible to significantly reduce the extension of the main frame and its weight, obtaining a higher stiffness / weight ratio. Added to this advantage is the reduced length of the uprights that run sideways to the engine, which allowed the Borgo Panigale engineers to design a compact bike, especially in the rider's seating area.
The chassis layout is completed by the trellis seat-post frame, fixed at the top to the "Front Frame" and screwed below the head of the rear bank.
