Piaggio LIBERTY MOT pass rate and common failures

What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with not working on dipped beam - it accounts for 29.2% of failed tests on this model.
- Then check not working and does not illuminate by the operation of both brake controls, the next two most common reasons.
- Age matters here: 91.94% of 3-5 year old examples pass, against 77.94% at 16+ years - a gap of 14 points.
- The most common advisory is excessively stiff or notchy (3.7% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 10,397 miles, which is the number to compare any advert against.
Pass rate by age
A single pass rate hides the most useful thing in this data: how the same model behaves at three years old and at fifteen.

| 3-5 years | 91.94% | 62 | |
| 6-10 years | 91.67% | 60 | |
| 11-15 years | 76.47% | 51 | |
