Yamaha FZ1S 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 missing - it accounts for 37.2% of failed tests on this model.
- Then check not working and has a serious fluid leak, the next two most common reasons.
- Age matters here: 93.33% of 11-15 year old examples pass, against 88.08% at 16+ years - a gap of 5.3 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 (9.3% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 29,181 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 | |
|---|---|---|---|
| 11-15 years | 93.33% | 135 | |
| 16+ years | 88.08% | 520 |
