What to check before the MOT

- Start with not working - it accounts for 13.3% of failed tests on this model.
- Then check has a serious fluid leak 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 (6.6% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 9,659 miles, which is the number to compare any advert against.
