Suzuki VZ800 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 38.1% of failed tests on this model.
- Then check missing and has a serious fluid leak, the next two most common reasons.
- Age matters here: 92.54% of 11-15 year old examples pass, against 83.6% at 16+ years - a gap of 8.9 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 (13.4% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 19,887 miles, which is the number to compare any advert against.
Pass rate by age

| Age at test | Pass rate | Tests | |
|---|---|---|---|
| 11-15 years | 92.54% | 67 | |
| 16+ years | 83.6% | 372 |
