Vespa PX 80 with Malossi 139ccm cylinder

In many cases, the TüV requires a performance report to enter changes to the engine.

Next to the 135cc DR cylinder is the  Malossi cylinder with 139ccm one of the most popular cylinders to help the little PX on the jumps. So also in this case, our customer Timur needs such a diagram for the demonstration and entries with 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 tester can correctly assign the diagram to the vehicle. All scooters with gear shift and four gears are usually measured in third gear. This information is also noted in the diagram.

      So that the changed maximum speed can also be entered during the test, we carry out a performance versus speed run. Here all available aisles are simply extended.
