Harley-Davidson FXDWG 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 not working - it accounts for 60.7% of failed tests on this model.
- Then check does not conform to the specified requirements and missing, the next two most common reasons.
- Age matters here: 98.04% of 6-10 year old examples pass, against 90.19% at 16+ years - a gap of 7.9 points.
- 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 (21.2% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 23,986 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.

|---|---|---|---|
| 6-10 years | 98.04% | 51 | |
| 11-15 years | 87.23% | 47 | |
| 16+ years | 90.19% | 520 |
