Cylinder Malossi 135cc MRH aluminum intake to the crankcase or laminated to the cylinder for Vespa Primavera - ET3 - Ape 50

Description

Cylinder Vespa ET3 125: THE NEW LEGEND Malossi is proud to present to their audience the total rebirth of a true legend, one of the most enduring and successful projects that have ever been associated with our brand: the new and amazing cylinder for Vespa ET3 125. This time entirely in aluminum. The history of this thermal group begins in 1982, when, for the first time in a cast iron cylinder with this segment, is used as an o-ring seal between the cylinder head and, a refined solution that still represents the state of art . Malossi took a blank sheet to rewrite his project, conceiving it anew from the roots, innovating and presenting to his audience a cylinder that goes to everything right in the glorious family of MHR thermal units. THE' Aluminum has taken the place of cast iron and has been completely redesigned the seat of the reed valve, authentic revolution able to solve the original admission deficiencies Vespa already since 1982, and now equipped with a crossbar to ensure greater stability to the piston wing. The capacity rises to 130 cubic centimeters, while the six racking are the result of the know-how and technology acquired over decades of competitions in the scooter world and applied for the first time in history to a Vespa cylinder can reach high power levels and speeds up to 11,000 rpm. Even the exhaust system has been completely redesigned and now presents a diagram with booster, a racing solution that provides a wide area of ??the flue gas expulsion reducing the fatigue of the piston rings. Malossi's philosophy has always been to provide a comprehensive and powerful plug and play kit. It could not, therefore, miss the total reissue of overall lamellar collector to the specific cylinder for this cylinder unit (code = 2016319 - only for Vespa ET3 SPRING). Massive studies and simulations on fluid made with futuristic software made it possible to connect in a perfect way the collectors obtaining an overall almost completely straight, able to ensure the best possible passage from the carburetor to the admission, all while remaining perfectly inside the body Vespa. E 'unpublished also the piston, made specifically for this cylinder, now ultralight, single ring and high performance. THESE COMPONENTS ARE INTENDED FOR USE ONLY RACING-SPORTS
