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.

Pass rate by test year

first-time MOT pass rate in each calendar year both bikes were tested
Test year SYM Jet 14 125 E4 LC Honda PCX 125
2022 82.7% 80.3%
2023 75.5% 80.2%
2024 80.6% 80.9%
2025 78.9% 81.6%

Each year mixes bikes of different ages, so a fleet that is getting older tends to slip.
