What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with not working - it accounts for 52.8% of failed tests on this model.
- Then check too low and missing, 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 (10.7% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 29,337 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.

|---|---|---|---|
| 11-15 years | 88.89% | 36 | |
| 16+ years | 84.63% | 4,022 |
