The choice of materials is the first step, but a meticulous work on the geometries is also required, which develops in two different directions: the first to check that new materials do not present application difficulties, the second to improve and lighten the existing components.
“Many components were optimised by thinning the thicknesses and introducing lightening originally not present. With the same approach, starter gears and camshafts have been machined with additional lightening holes on the lobes and longitudinally by decreasing the cross-section over the entire length of the shaft.
42% of the components were redesigned to gain, in some cases, only a few dozen grams. When added to one another, though, the gain was quite sizeable and amounted to an overall reduction of 6.17 lb in comparison with our Panigale V4 S engine.
A component for which we managed to achieve a remarkable weight reduction is the oil pump assembly; we drastically simplified the assembly design and reduced the number of recovery pumps from 3 to 2. Thanks to the completely new design of inner pump ducts we managed to keep the assembly function unchanged, that is, the new pumps drain the oil from the same areas and with the same efficacy as the old system.”
