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 GTR beats 0 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 GTR.

Pass rate by registration year

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

Best year to buy used: 2008 (62.6% pass). Weakest: 2005 (55.3%).

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.

CPI GTR FAQ

answers computed from the data above · terms in the glossary

Is the CPI GTR reliable?

The CPI GTR is less reliable than average for its class: 62.2% of its 621 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #5136 of 5426 models.

What does a GTR fail its MOT on most?

lighting and signalling — 39% of all defects recorded against failed GTR tests.

What is the best year of GTR to buy used?

By first-time pass rate, 2008-registered examples do best (62.6%) and 2005 worst (55.3%). Condition and history still trump the year.
