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 PS beats 4 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 PS.

Pass rate by registration year

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

Best year to buy used: 2009 (89.3% pass). Weakest: 2011 (73.2%).

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.

HONDA PS FAQ

answers computed from the data above · terms in the glossary

Is the HONDA PS reliable?

The HONDA PS is more reliable than average for its class: 80.8% of its 897 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #3420 of 5426 models.

What does a PS fail its MOT on most?

brakes — 30% of all defects recorded against failed PS tests.

What is the best year of PS to buy used?

By first-time pass rate, 2009-registered examples do best (89.3%) and 2011 worst (73.2%). Condition and history still trump the year.

How many miles will a PS last?

The median PS shows 14,598 miles at test, and examples around 30k miles still pass 77.2% of the time — mileage alone rarely kills one.
