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 NSC beats 4 of its 4 closest rivals (PEUGEOT SPEEDFIGHT, PIAGGIO ZIP, PIAGGIO NRG).

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 NSC.

Pass rate by registration year

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

Best year to buy used: 2018 (91.4% pass). Weakest: 2012 (78.8%).

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 NSC FAQ

answers computed from the data above · terms in the glossary

Is the HONDA NSC reliable?

The HONDA NSC is more reliable than average for its class: 84.9% of its 9,547 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #2515 of 5426 models.

What does a NSC fail its MOT on most?

brakes — 26% of all defects recorded against failed NSC tests.

What is the best year of NSC to buy used?

By first-time pass rate, 2018-registered examples do best (91.4%) and 2012 worst (78.8%). Condition and history still trump the year.

How many miles will a NSC last?

The median NSC shows 7,376 miles at test, and examples around 40k miles still pass 76.9% of the time — mileage alone rarely kills one.
