Thermal group Malossi MHR Ø 63 aluminum CVF2 pin Ø 15 Vespa PX 125 2T 3117163

<p>This 74cc cylinder kit is an exact replica of the model used to break the world record at the Nardo test track. Made of high-quality cast iron, the cylinder features 5 transfer ports and a standard exhaust, a single-ring piston with a 49.5 mm diameter, and a one-piece high-compression cylinder head. The kit includes all necessary mounting components, such as gaskets and fixing parts. The performance of this cylinder is exceptional, reaching up to 15–16 HP with the right setup. Its torque is impressive, standing out especially in the high RPM range, as expected from a racing cylinder. Although very similar to the “Due Plus” model with modular head, this kit has been designed to set new performance standards and has been used to break records on the track. We recommend using a carburetor of at least 19 mm and a sport or racing exhaust to get the most out of this cylinder. It’s important to note that some users may notice two small holes under the intake port — these are required for proper cylinder lubrication and do not affect performance.</p>
