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 Sukida SK 125 T-21 Honda CG125
2011 61.5% 70.6%
2012 69.4% 70.6%
2013 64.7% 69.4%

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