Carter MALOSSI V-One, aspirazione a valvola- Vespa PX 125-150 Elestart

The technical and technological advancement of Malossi is the greatest strength of our products, the reason why we are convinced that we have created one of the best crankcases ever produced. Strengths In every square millimetre of the crankcase there is an innovative drive that jumps out at the eyes of even the most inexperienced tuner. Gravity die casting, which differentiates these crankcases from the original models made using a die-casting process, combined with the use of modern shell moulding cores, allows us to achieve better and more precise internal shapes. Gravity casting has allowed us to strategically increase the sections in the most stressed areas and to subject the crankcases to a tempering treatment after casting, thus achieving very high mechanical strength. These products are made of a light aluminium alloy Al Si 7 Mg (EN AB and AC 42000) of the highest quality containing the following in the right quantities: Silicon, to increase mechanical resistance, Manganese, for better resilience and resistance to corrosion, Copper and Magnesium, to improve machinability. Machining of the casings is carried out entirely in our workshop using a CAD/CAM process and performed on high-precision CNC machining centres. All bearing and closing surfaces are machined with diamond tools that guarantee very low surface roughness values and virtually perfect fits. Advantages Both crankcases share a number of basic features such as, for example, a reinforced front arm with stress relief ribs and sections with a calculated profile to allow the correct flow and channelling of stresses and ensure better strength. In both models there are pins for the brake shoes, which are installed in-house with presses capable of applying the necessary forces to make the couplings required by our designers. In addition to the brake shoes, the housings are supplied with the M7 studs required for mounting the gear selector. Finally, no version excludes the original electric starter, the actuator of which can be mounted in the special plate in the volute. Fluid dynamics has finally been implemented! The fact that we have equipped our standard models with transfer cases suitably profiled and sized to fit perfectly with our Ø 63 cylinders, without however excluding the possibility of fitting other thermic units and indeed offering an increase in performance even with the latter, exempts tuners from the obligation to machine the crankcases to fit higher performance cylinders. The M7 studs for cylinder mounting are also included in the package! Thanks to the measures listed, achieving more power is no longer a problem. Even the usual problem of oil leakage from the crankcase has been solved thanks to: Increased pump crankcase walls, which also further contributes to the mechanical strength of the crankcase Use of M8 hanger bolts instead of the original M7 High-precision machining of the locking planes. We have eliminated the crankcase gasket, which was deteriorating and was mainly responsible for oil leakage. Now the crankcases are perfectly matched and sealed with gasket paste, which is resistant to even the highest operating temperatures!
