This DVA (dual damping flywheel) comes with two weights, one integral with the crankshaft and one with the gearbox mainshaft with an intervening flexible damping system.the resonance points, located between 800 and 2200 rpm on a conventional system, are shifted toward lower rpms outside the service range.The clutch engagement mechanism, located between the dual flywheel and gearbox, consists of a rigid plate (unsprung) that improves gear manoeuvrability due to its reduced inertia.
