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
On first-time pass rate the GTS beats 1 of its 3 closest rivals (PIAGGIO X9, HONDA Forza 300/350, PIAGGIO VESPA GTS 300 SUPER).
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 GTS.
Pass rate by registration year
Best year to buy used: 2011 (92.6% pass). Weakest: 2008 (81.2%).
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.

What is the best year of GTS to buy used?
By first-time pass rate, 2011-registered examples do best (92.6%) and 2008 worst (81.2%). Condition and history still trump the year.
How many miles will a GTS last?
