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.

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

first-time MOT pass rate in each calendar year both bikes were tested

Test year	CCM 404DS	Kawasaki ER5
2018	79.0%	78.3%
2019	81.9%	77.1%
2020	80.4%	79.4%

2024	85.3%	77.8%
2025	90.9%	79.6%

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