# Triumph Pi MOT reliability: pass rate and common failures | RegFlags

The Triumph Pi passed its MOT first time 75% of the time, but from only 4 MOT tests, so treat it as a rough guide. See pass rates by year, common failures and typical mileage.

- First-time MOT pass rate: 75%
- MOT tests analysed: 4 (DVSA anonymised MOT data, 2025)
- Most common failure area: Brakes

These figures come from only 4 MOT tests. With so few cars, a single pass or fail changes the percentages a lot, so treat them as a rough guide rather than a true average.
