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 DAYTONA beats 2 of its 4 closest rivals (YAMAHA YZF-R1, HONDA CBR900RR, HONDA CBR1100XX).
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 DAYTONA.
Pass rate by registration year
Best year to buy used: 1967 (93.9% pass). Weakest: 1993 (79.3%).
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.
