Px 125 (Vespa): above-average pass rates, with caveats
Across 1,333 MOT tests, the Px 125 (Vespa) returns 84.4% first-time pass — above the UK fleet average. The single most-logged Major fail is direction indicator lamp missing. Lamp missing or inoperative and a stop-lamp out round out the top three. Average tested mileage sits at 12,467, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a PX 125 (vespa)?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
