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 TW beats 0 of its 4 closest rivals (YAMAHA YBR 125, HONDA CG125, HONDA CBF125).

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 TW.

Pass rate by registration year

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

Best year to buy used: 2017 (63.8% pass). Weakest: 2016 (49.7%).

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.

KSR Moto TW FAQ

What is the best year of TW to buy used?

By first-time pass rate, 2017-registered examples do best (63.8%) and 2016 worst (49.7%). Condition and history still trump the year.
