What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 61.5% of failed tests on this model.
- Then check tread depth is below minimum requirements of 1.0mm and does not conform to the specified requirements, 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 11,564 miles, which is the number to compare any advert against.
