KTM 390 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 57.1% of failed tests on this model.
- Then check not working and tread depth is below minimum requirements of 1.0mm, 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 (8.2% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 9,263 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 | 86.05% | 301 | |
| 11-15 years | 90.54% | 74 |

| 1 | Missing | 57.1% | 16 | |
| 2 | Not working | 25% | 7 | |
| 3 | Tread depth is below minimum requirements of 1.0mm | 25% | 7 | |
| 4 | Excessively binding | 21.4% | 6 | |
| 5 | Does not conform to the specified requirements | 14.3% | 4 | |
| 6 | Excessively loose | 14.3% | 4 | |
| 7 | Does not illuminate by the operation of both brake controls | 10.7% | 3 | |
| 8 | Has a serious fluid leak | 10.7% | 3 | |
| 9 | Noise is clearly in excess of that emitted by a similar motorcycle fitted with a standard silencer in average condition | 10.7% | 3 | |
| 10 | So loose it is likely to fail | 10.7% | 3 |
Most common advisories
Not a failure and not a legal requirement to fix - but an advisory that repeats year after year is money the next owner spends.

| 3 | Has a serious fluid leak | 4.7% | 18 | |
| 4 | Excessively loose | 4% | 15 | |
| 5 | Excessively binding | 3.2% | 12 | |
| 6 | Indicates excessive fluctuation of brake effort | 2.9% | 11 | |
| 7 | Excessively tight | 1.8% | 7 | |
| 8 | Tread not clearly visible | 1.8% | 7 | |
