400 cc motor
Met een maximumvermogen van 26 kW (35,4 pk) bij 7500 tpm en een maximumkoppel van 37,7 Nm bij 5500 tpm, maakt de 400 cc-motor zijn debuut op de nieuwe Beverly, gebouwd op de basis van de vorige 350 cc-motor die hij vervangt. Het wezenlijke verschil is echter niet alleen de grotere capaciteit: hoewel de ingenieurs van Piaggio uitgingen van een toch al uiterst efficiënte motor, concentreerden ze zich op meerdere aspecten met als doel de mechanische en thermodynamische prestaties verder te verbeteren en trillingen en geluid te verminderen.
De transmissie is ook herzien, met de automatische continu variabele transmissie (CVT) die een nieuwe lay-out heeft, ontwikkeld om de koeling van de riem te verbeteren, waaraan ook een ventilator met een grotere diameter bijdraagt.
Net als de 300 hpe maakt ook de 400 hpe gebruik van een iridium-bougie en wordt hij aangestuurd door de krachtige Magneti Marelli MIUG4 ECU.

400 hpe engine
Accredited with maximum power of 26 kW (35.4 HP) at 7500 rpm and maximum torque of 37.7 Nm at 5500 rpm, the 400 hpe engine makes its début on the new Beverly, built on the base of the previous 350 cc unit which it replaces. The substantial difference, however, is not simply the increased capacity: although starting from an already extremely efficient engine, the Piaggio engineers focused on multiple aspects with the goal of further improving mechanical and thermodynamic performance, as well as reducing vibrations and noise.
The use of a longer rod with optimised weight, as well as a piston that has also been lightened and moulded in aluminium alloy - solutions that are not common, usually dedicated to high-level motorcycle applications - contributed to reducing the alternating inertia forces, resulting in less vibration transmitted to the vehicle. All of this translates into greater overall comfort, particularly at cruising speed - an aspect that highlights the suburban touring character of the Beverly 400 hpe.
On the 400 hpe, which maintains the exceptional characteristics of light weight and compact size as the 350 (weight and bulk remain substantially the same), an innovative system patented by Piaggio makes its début, called PCV - Positive Crankcase Ventilation: comprising two blades built into the engine crankcase, it aims to reduce pumping losses, thereby favouring an increase in power.
Engine output, in terms of both power and torque, benefits from a new, specific intake line and optimised valve lifting. A new progressive type chain tensioner, on the other hand, contributes to quieter timing operation.
Overall efficiency benefits from several changes in various areas: these include optimisation of the combustion chamber using CFD calculations, a new high pressure injector that atomises the fuel more and the use of a less viscous engine oil (5W-40).
The 400 hpe engine is recognisable at a glance thanks to a new dedicated silencer with aggressive dual pipes, a clearly motorcycle-inspired solution.
The transmission has also been revisited, with the automatic continuously variable transmission (CVT) that has a new layout, developed to improve cooling of the belt, to which a larger diameter fan also contributes.
Like the 300 hpe, the 400 hpe also uses an iridium spark plug and is controlled by the powerful Magneti Marelli MIUG4 ECU.
