Description
Vespa ET3 125 Cylinder
THE NEW LEGEND
Malossi is proud to introduce to its public the total renewal of a real legend, one of the most long-lived and successful projects ever linked to our trade mark: the new and amazing cylinder for Vespa ET3 125. This time wholly aluminium made.
The story of this cylinder kit starts in 1982 when, for the first time in a cast iron cylinder with this ring, an oring is used as seal gasket between head and cylinder: a refined solution representing so far the state of the art.
Malossi has taken a blank paper to redesign its project, drawing it up new from the roots, thus renewing and releasing a cylinder which rightfully joins the famous range of MHR cylinder kits.
Aluminium replaced cast iron and the reed valve seat has been totally redesigned, a real revolution able to fill the gaps of the original Vespa intake already since 1982 and now equipped with a centre support in order to grant a higher stability to the piston ring.
Displacement increases to 130cc, whereas the six ports are the result of the know-how and technology gained during decades of scooter races. Now, for the first time in the history, they are fitted on a Vespa cylinder which can reach very high horse powers and revolutions up to 11.000 rpm.
The exhaust system as well has been completely renewed and it is equipped with a booster now, a racing solution which grants a wide expulsion surface of the burnt gases, thus reducing the piston ring wear.
Malossi philosophy has always been to supply a "plug and play", complete and powerful kit. Therefore, the total new edition of the reed-valve block specific for this cylinder kit couldn't miss (code = 2016319 - only for VESPA ET3 PRIMAVERA).
Thanks to a considerable number of studies and fluid dynamics simulations created using futuristic softwares, manifolds have been perfectly machined so as to obtain an almost straight system, able to ensure the optimal passage from carburettor to intake, while perfectly remaining inside the Vespa body.
The piston is brand new as well, specifically designed for this cylinder, now super light, with one piston ring and very high performances.
