Caractéristiques techniques Une autre révolution dans la philosophie de construction des moteurs à 2 temps: les ailettes de refroidissement ont été dimensionnées pour optimiser le flux thermique de la chambre vers l’extérieur, mais à présent elles sont aussi profilées selon des simulations modernes pour permettre la majeure pénétration possible de l’air provenant de l’installation de refroidissement qui effleure la tête avec un incrément du rendement de plus de 10% par rapport à un système traditionnel à ailettes droites. La chambre de combustion, au profil hémisphérique, a été usinée avec…

Pour monter la culasse V4 HEAD dans les moteurs Piaggio 125 - 250 ie 4T LC en production du Septembre 2014 équipés par culbuteurs à rouleaux dans la culasse, il faut acheter même l'arbre à cames Malossi (Réference = 5911962) en plus de pièces Piaggio.

Caractéristiques techniques Matériaux: alliage spécial d'aluminium moulé sous pression. Géométrie des surfaces d'échange thermique recalculée et augmentée. Usinage sur machines à contrôle numérique très précises avec outils de diamants. Tenue de la compression par joints en Viton. Chambre de combustion émisphérique avec squish et bougie au centre.

Caractéristiques techniques Materaiux: Alliage spéciale d'alluminium a haut coefficient d'échange thermique. Géométrie des superficies d'échange thermique augmenté et recalculé. Chambre de combustion complètement redessinée pour un rapport de compression élevé et à haute turbulances. Travail réalisé sur machine outils à commande numérique.
