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 NSR125 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 NSR125.

Pass rate by registration year

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 NSR125 FAQ

answers computed from the data above · terms in the glossary

Is the HONDA NSR125 reliable?

The HONDA NSR125 is less reliable than average for its class: 59.9% of its 10,030 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #5218 of 5426 models.

What does a NSR125 fail its MOT on most?

lighting and signalling — 30% of all defects recorded against failed NSR125 tests.

What is the best year of NSR125 to buy used?

By first-time pass rate, 2005-registered examples do best (70.7%) and 1991 worst (53.4%). Condition and history still trump the year.

How many miles will a NSR125 last?

The median NSR125 shows 17,443 miles at test, and examples around 50k miles still pass 64.4% of the time — mileage alone rarely kills one.
