What to check before the MOT

Built from this model's own failure record, not general advice.

Start with missing - it accounts for 86.2% 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 (12.3% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 9,642 miles, which is the number to compare any advert against.

3-5 years	89.13%		727
6-10 years	90.61%		607
