LAMBRETTA LI150 SERIES 2
The pass rate is the MOT first-time pass: a roadworthiness check of the items an MOT covers (brakes, lights, tyres, steering, structure, emissions), not a full mechanical inspection of engine or gearbox internals. It is a reliability signal, not a complete measure of mechanical reliability. What this measures.
Pass rate over time
The LI150 SERIES 2's first-time pass rate has fallen 10.3 points since 2016, 100.0% to 89.7%.

Best year to buy used: 1961 (93.8% pass). Weakest: 1960 (93.6%).
