SHERCO 2005
 |
Cette année encore, l'équipe technique de Sherco Trial a travaillé pour proposer à nouveau la gamme de
motos de trial la plus complète du marché. Ainsi, chacune des Sherco 0.5, 0.8, 1.25 et 2.9 reçoit des
améliorations spécifiques. la gamme Sherco de trial 2005 est complétée par un nouveau modèle prévu pour cet automne
vraiment prestigieux. La nouvelle moto équipée d'un moteur 4 temps entièrement développé par PXC, le
Département Compétition Trial de Sherco et dirigé par Josep Rovira Paxau. PXC montre à nouveau son
professionnalisme en présentant la moto de trial 4 temps la plus légère et la plus compacte du marché (dixit Sherco).
Ce nouveau moteur a été développé secrètement durant deux ans.
Il s'agit d'un moteur de 317cc à course courte, un arbre à cames en tête et 4 soupapes. Le poids du moteur
est très contenu et Sherco a travaillé à fond pour qu'il puisse offrir des niveaux de puissance, couple moteur,
traction et efficacité supérieurs à ceux obtenus avec des moteurs à 2 temps
Pour la photo il faudra patienter encore un peu , la concurrence est sur les dents et on entend pas chez Sherco donner trop d’informations , toutefois en regardant de plus prés les caractéristiques techniques , on comprend bien que toute la partie cycle sera la même que les modèles 2.5 et 2.9
Ce qui change :
0,5 : Nouvelle décoration 2005, pas de changement technique
0.8 : Nouvelle cylindrée de 79cc dans le but de s'adapter aux différentes
