Harley-Davidson STREET MOT pass rate and common failures

What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 33.3% of failed tests on this model.
- Then check not working and excessively stiff or notchy, 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 (12.1% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 9,639 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.
| Age at test | Pass rate | Tests | |
|---|---|---|---|
| 6-10 years | 84.25% | 273 |
