Reducing the weight also means further reducing inertia and modifying the gyroscopic forces determining the balance of the vehicle as a whole. To satisfy the ambitious objectives set by Aprilia in terms of weight and rigidity, the best available materials and production techniques were used. The wheel is made from Anticorodal 5051 forged aluminium using an hydraulic forging press with a power of 8000 tonnes. A finite element analysis then enabled the best possible design to be identified and, after testing various models, a version with six spokes dividing towards the edge of the channel was chosen. The choice was not made exclusively on the basis of aesthetic criteria.
