Pass rate over time

first-time pass rate by test year · 2017–2025

The CODE's first-time pass rate has risen 9.1 points since 2017, 62.9% to 72.0%.

Pass rate by mileage

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

A low-mileage CODE passes first time 71.5% of the time; by 20k that's 52.2%.

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 CODE beats 0 of its 4 closest rivals (YAMAHA YBR 125, HONDA CG125, HONDA CBF125).

YAMAHA YBR 125 71.0% pass · 125k tests HONDA CG125 72.2% pass · 89.3k tests HONDA CBF125 73.3% pass · 84.4k tests GILERA RUNNER 70.8% pass · 69.9k 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 CODE.

Pass rate by registration year

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

Best year to buy used: 2017 (78.2% pass). Weakest: 2014 (61.3%).

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 CODE FAQ

answers computed from the data above · terms in the glossary

Is the GENERIC CODE reliable?

The GENERIC CODE is less reliable than average for its class: 65.8% of its 1,318 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4977 of 5426 models.

What does a CODE fail its MOT on most?

brakes — 26% of all defects recorded against failed CODE tests.

What is the best year of CODE to buy used?

By first-time pass rate, 2017-registered examples do best (78.2%) and 2014 worst (61.3%). Condition and history still trump the year.

How many miles will a CODE last?

The median CODE shows 9,535 miles at test, and examples around 20k miles still pass 52.2% of the time — mileage alone rarely kills one.
