Vespa PX 80 with Malossi 139 cc cylinder
In many cases, the TÜV requires a performance certificate in order to register modifications to the engine. In addition to the
135cc DR cylinder the 139cc Malossi cylinder is one of the most popular cylinders for giving the little PX a boost. As in this case, our customer Timur needs such a diagram for the presentation and registration at the TÜV.

When measuring according to DIN on the Amerschläger P4 test bench, we have to enter the key data of your engine in the diagram so that the inspector can assign the diagram to the vehicle correctly. All scooters with gears and four gears are usually measured in third gear. This information is also noted in the diagram.
To ensure that the modified maximum speed can also be entered during the test, we also carry out a power vs. speed run. Here, all available gears are simply used.
