Aprilia RS125 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 - it accounts for 36.7% of failed tests on this model.
- Then check missing and insecure, the next two most common reasons.
- Age matters here: 84.29% of 3-5 year old examples pass, against 72.71% at 16+ years - a gap of 11.6 points.
- The most common advisory is noise is clearly in excess of that emitted by a similar motorcycle fitted with a standard silencer in average condition (7.4% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 14,063 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.
| Age at test | Pass rate | Tests | |
|---|---|---|---|
| 3-5 years | 84.29% | 70 | |
| 6-10 years | 73.55% | 155 | |
| 11-15 years | 66.67% | 90 | |
| 16+ years | 72.71% | 480 |

Most common advisories
Not a failure and not a legal requirement to fix - but an advisory that repeats year after year is money the next owner spends.
