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 Lifan LF 125 T-26 Aero Honda CBF125
2014 63.8% 72.0%
2015 56.6% 71.8%
2016 57.3% 72.2%
2017 51.3% 71.3%

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