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 SKP beats 2 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 SKP.

Pass rate by registration year

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

Best year to buy used: 2001 (69.4% pass). Weakest: 2005 (55.6%).

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.

GILERA SKP FAQ

answers computed from the data above · terms in the glossary

Is the GILERA SKP reliable?

The GILERA SKP is less reliable than average for its class: 67.0% of its 1,745 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4904 of 5426 models.

What does a SKP fail its MOT on most?

lighting and signalling — 42% of all defects recorded against failed SKP tests.

What is the best year of SKP to buy used?

By first-time pass rate, 2004-registered examples do best (69.4%) and 2005 worst (55.6%). Condition and history still trump the year.

How many miles will a SKP last?

The median SKP shows 8,882 miles at test, and examples around 20k miles still pass 57.9% of the time — mileage alone rarely kills one.
