What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 36.7% of failed tests on this model.
- Then check has a serious fluid leak and not working, 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 (10.8% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 18,855 miles, which is the number to compare any advert against.

|---|---|---|---|
| 6-10 years | 86.67% | 30 | |
| 11-15 years | 86.92% | 413 |
