What to check before the MOT

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

Start with not working - it accounts for 45.1% of failed tests on this model.
Then check too low and has a serious fluid leak, 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 (7.7% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 26,720 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.
