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 404E	Suzuki DR-Z400S
2008	73.9%	80.5%
2009	68.8%	78.2%
2010	85.7%	78.9%

2014	80.6%	78.5%
2016	90.0%	78.4%

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

Pass rate by mileage
