What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 57.9% of failed tests on this model.
- Then check not working and excessively binding, the next two most common reasons.
- 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 (6.7% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 10,299 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 | 73.67% | 1,732 | |
| 6-10 years | 71.39% | 734 |
