What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with excessively stiff or notchy - it accounts for 23.8% of failed tests on this model.
- Then check excessively binding and excessively loose, 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 (7.4% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 14,315 miles, which is the number to compare any advert against.

|---|---|---|---|
| 3-5 years | 71.88% | 32 | |
| 6-10 years | 81.65% | 278 |
