First-time outcomes on normal tests, 2005–2025. "Most common failure" is the component group with the most recorded defects on failed tests. Read pass rates against test counts: a smaller sample is noisier. Source: DVSA anonymised MOT results.
"Vs comparable bikes" is the first-time pass rate minus the rate expected for each bike's own mix of age, mileage and test class, in percentage points: positive means better than comparable bikes. How this works.
What fails, side by side
| Component | Honda CMX 500 A2-L | Kawasaki ZX-6R |

A test that fails on two components counts once in each. Component links go to the bikes most likely to fail on it.
Pass rate by test year
| Test year | Honda CMX 500 A2-L | Kawasaki ZX-6R |
|---|---|---|
| 2023 | 95.4% | 79.8% |
| 2024 | 94.7% | 80.3% |
