The Vespa never dies

1983: the 68,5 aluminum cylinder is born, a turning point in the development of the Vespa.

In Nicasil aluminum, with super light piston, 1.2 mm semi-trapezoidal bands, the new cylinder immediately becomes 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 aluminum, is completely redesigned in the transfer pipes, both main and rear, and in the exhaust pipe, and presented in three versions:

SPORTS: Art. 3116346
MHR: Art. 3116349
MHR stroke 60: Art. 3116129
The MHR version differs from the SPORT, as well as in the exhaust port, also in the decidedly racing transfer diagrams.

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

2016: completing the long list of updates comes the new piston with a black coat, the result of a molybdenum sulphide treatment. The semi-trapezoidal segmentation and the crown remain unchanged, while the real innovation is in the totally 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 completely revised ribbing ensures a lightweight design and even greater strength.
Attention: it is absolutely essential to use fuel taps with increased capacity.
