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 CBR 125 RW-B beats 3 of its 3 closest rivals (YAMAHA YZF-R125, HONDA CBR125R, HONDA CBR 125 R-4).

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 CBR 125 RW-B.

Pass rate by registration year

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

Best year to buy used: 2012 (78.5% pass). Weakest: 2011 (75.1%).
