Pass rate by mileage

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

A low-mileage FORMULA passes first time 74.4% of the time; by 20k that's 70.4%.

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 FORMULA beats 3 of its 4 closest rivals (PEUGEOT SPEEDFIGHT, PIAGGIO ZIP, PIAGGIO NRG).

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 FORMULA.

Pass rate by registration year

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

Best year to buy used: 1998 (81.1% pass). Weakest: 2004 (54.8%).

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.

ITALJET FORMULA FAQ

answers computed from the data above · terms in the glossary

Is the ITALJET FORMULA reliable?

The ITALJET FORMULA is less reliable than average for its class: 70.5% of its 2,801 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4691 of 5426 models.

What does a FORMULA fail its MOT on most?

lighting and signalling — 40% of all defects recorded against failed FORMULA tests.

What is the best year of FORMULA to buy used?

By first-time pass rate, 1998-registered examples do best (81.1%) and 2004 worst (54.8%). Condition and history still trump the year.

How many miles will a FORMULA last?

The median FORMULA shows 8,252 miles at test, and examples around 20k miles still pass 70.4% of the time — mileage alone rarely kills one.
