Vespa has been established since 1946 as a unique case of style and technology, to meet the demand for freedom of all generations and point the way for a world in which individual mobility is concerned, is identical to the emancipation.
2012 Vespa Quarantasei is one motorcycle model that is introduced by the Vespa with scooter edition. The body design of this motorbike is comfortable to use. 2012 Vespa Quarantasei has a maximum power at crankshaft of 8.7 kW at 8,250 rpm.
The single cylinder 125 cc 4 stroke, 3 valve, air cooled engine with electronic injection represents Piaggio Group's state of the art technology in scooter engines.
The new engine has been designed, developed and manufactured entirely in Pontedera, Piaggio's largest plant, which is one of the most advanced engine development and production centers in the world.
This engine is born from the challenge that the Piaggio Group has taken on: to provide an increasingly more evolved customer with a product that guarantees performance, reliability and safety while also leading the field in respect for the environment.
The innovative 3 valve timing which characterizes the Vespa Quarantasei engine allows optimization of the load motion in the cylinder both in terms of tumble and swirl as well as optimal positioning of the spark plug, increasing combustion performance and at the same time guaranteeing optimum cooling of the parts inside the head.
The cooling system was carefully analyzed, even through thermal fluid-dynamic simulations, in order to further improve performance, thereby obtaining significant reduction in terms of absorbed power and acoustics.
The injection system is state of the art for functionality and ride ability, with automatic idle control and closed-loop titer management with a lambda probe. The three dimensional maps of advance, titer and injection timing are managed by a new generation control unit.
Together with the trivalent catalytic converter, compliance with the Euro3 standard is more than guaranteed, even in anticipation of future standards which will be increasingly restrictive in terms of containment of polluting emissions.
