Convert Vespa PX80 to 125cc - with TÜV - all info - all parts here

Easily convert your Vespa PX80 to 125cc – Here's how:

Prices for Vespa PX models have been rising for years. The most affordable models are still the Vespa PX 80 / PX80 Lusso. The 80cc Vespas have the least power and are classified as the most expensive by insurance companies. Upgrading to 135cc or 139cc makes the scooter no longer legal with a 125cc license. Here, we'll show you how to easily convert a PX80 into a PX125 without having to modify the crankshaft or gearbox:
