Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the MRT beats 0 of its 4 closest rivals (PEUGEOT SPEEDFIGHT, PIAGGIO ZIP, PIAGGIO NRG).

PEUGEOT SPEEDFIGHT 65.2% pass · 83.7k tests PIAGGIO ZIP 71.3% pass · 79.0k tests PIAGGIO NRG 65.5% pass · 40.5k tests PEUGEOT VIVACITY 70.4% pass · 29.7k tests

Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the MRT.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 2013 (61.9% pass). Weakest: 2018 (56.2%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.

What is the best year of MRT to buy used?

By first-time pass rate, 2013-registered examples do best (61.9%) and 2018 worst (56.2%). Condition and history still trump the year.
