Pass rate over time

first-time pass rate by test year · 2010–2021

The XOR's first-time pass rate has risen 6.4 points since 2010, 68.6% to 75.0%.

Pass rate by mileage

how the XOR's first-time pass rate falls with the odometer · class average 73.4%

A low-mileage XOR passes first time 69.9% of the time; by 20k that's 55.7%.

First-time pass rate by odometer reading at test, 10,000-mile bands for this model. Mileage is the strongest reliability signal. See the full curve.

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 XOR beats 2 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 XOR.

Pass rate by registration year

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

Best year to buy used: 2010 (70.1% pass). Weakest: 2007 (63.2%).

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.

GENERIC XOR FAQ

answers computed from the data above · terms in the glossary

Is the GENERIC XOR reliable?

The GENERIC XOR is less reliable than average for its class: 66.7% of its 1,090 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4923 of 5426 models.

What does a XOR fail its MOT on most?

lighting and signalling — 29% of all defects recorded against failed XOR tests.

What is the best year of XOR to buy used?

By first-time pass rate, 2010-registered examples do best (70.1%) and 2007 worst (63.2%). Condition and history still trump the year.

How many miles will a XOR last?

The median XOR shows 8,332 miles at test, and examples around 20k miles still pass 55.7% of the time — mileage alone rarely kills one.
