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 NC29 beats 2 of its 4 closest rivals (KAWASAKI ER5, SUZUKI GS500, SUZUKI AN400).

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 NC29.

Pass rate by registration year

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

Best year to buy used: 1997 (90.2% pass). Weakest: 1990 (70.0%).

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 NC29 FAQ

answers computed from the data above · terms in the glossary

Is the HONDA NC29 reliable?

The HONDA NC29 is less reliable than average for its class: 78.1% of its 521 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3896 of 5426 models.

What does a NC29 fail its MOT on most?

lighting and signalling — 31% of all defects recorded against failed NC29 tests.

What is the best year of NC29 to buy used?

By first-time pass rate, 1997-registered examples do best (90.2%) and 1990 worst (70.0%). Condition and history still trump the year.

How many miles will a NC29 last?

The median NC29 shows 32,640 miles at test, and examples around 50k miles still pass 77.3% of the time — mileage alone rarely kills one.
