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 Honda GL1200DG BMW R1150
2006 81.4% 91.8%
2007 90.7% 90.6%
2008 78.9% 89.3%
2009 80.0% 87.4%
2010 87.8% 88.3%

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