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 Motorini GP 50 Peugeot Speedfight
2020 77.6% 72.0%
2021 74.4% 71.0%
2022 70.8% 71.7%
2023 65.5% 71.0%

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