Pass rate over time
The NHX's first-time pass rate has fallen 8.2 points since 2013, 88.2% to 80.0%.
Pass rate by mileage
A low-mileage NHX passes first time 81.7% of the time; by 30k that's 65.7%.
First-time pass rate by odometer reading at test, 10,000-mile bands for this model. Mileage is the strongest reliability signal. See the full curve.

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 NHX beats 3 of its 4 closest rivals (YAMAHA YBR 125, HONDA C90, HONDA CG125).
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 NHX.
Pass rate by registration year
Best year to buy used: 2010 (80.4% pass). Weakest: 2011 (73.9%).
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 NHX FAQ
Is the HONDA NHX reliable?
The HONDA NHX is more reliable than average for its class: 75.6% of its 505 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4230 of 5426 models.
What does a NHX fail its MOT on most?
brakes — 33% of all defects recorded against failed NHX tests.
What is the best year of NHX to buy used?
By first-time pass rate, 2010-registered examples do best (80.4%) and 2011 worst (73.9%). Condition and history still trump the year.
How many miles will a NHX last?
The median NHX shows 12,125 miles at test, and examples around 30k miles still pass 65.7% of the time — mileage alone rarely kills one.
