What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with not working - it accounts for 34.1% of failed tests on this model.
- Then check missing 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 (15.2% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 14,681 miles, which is the number to compare any advert against.
Pass rate by age

|---|---|---|---|
| 3-5 years | 76.15% | 109 | |
| 6-10 years | 71.63% | 141 |
