What to check before the MOT

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

Start with missing - it accounts for 100% of failed tests on this model.
Then check too high and not working on dipped beam, 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 (3.7% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 4,956 miles, which is the number to compare any advert against.

Pass rate by age

A single pass rate hides the most useful thing in this data: how the same model behaves at three years old and at fifteen.
