Description
The Vespa never dies

1983: the Ø 68.5 aluminium cylinder is born, a turning point in the development of the Vespa.

Made of Nicasil aluminum, with a super light piston, 1.2 mm semi-trapezoidal rings, the new cylinder immediately became a legend, a real must for all enthusiasts.

2008: the cylinder is updated, with the addition of the head with hemispherical combustion chamber and central spark plug.

2013: the cylinder, although still made of Nicasil aluminium, is completely redesigned in the transfer ducts, both main and rear, and in the exhaust duct, and presented in three versions:

SPORT: Art. 3116346
MHR: Art. 3116349
MHR Corsa 60: Art. 3116129
The MHR version differs from the SPORT not only in the exhaust port, but also in the decidedly racing transfer diagrams.

The perfect centering between the head and the cylinder is guaranteed by two centering bushings placed on two studs, while the O-ring ensures a perfect seal.

2016: completing the long list of updates comes the new piston with a black skirt, the result of a molybdenum sulphide treatment. The semi-trapezoidal segmentation and the crown remain unchanged, while the real innovation is in the completely new mold, in which the new slots allow not only a perfect connection with the latest generation of the cylinder, but also interchangeability with its previous versions. The ribs, completely revisited, ensure a very light design and even greater resistance.
