The SGX's first-time pass rate has fallen 13.0 points since 2005, 78.6% to 65.6%.
Pass rate by mileage
A low-mileage SGX passes first time 78.7% of the time; by 30k that's 84.3%.
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 SGX 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 SGX.
Pass rate by registration year
Best year to buy used: 2003 (78.7% pass). Weakest: 1997 (73.4%).
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 SGX FAQ
Is the HONDA SGX reliable?
The HONDA SGX is more reliable than average for its class: 76.1% of its 8,795 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4171 of 5426 models.
What does a SGX fail its MOT on most?
lighting and signalling — 32% of all defects recorded against failed SGX tests.
What is the best year of SGX to buy used?
By first-time pass rate, 2003-registered examples do best (78.7%) and 1997 worst (73.4%). Condition and history still trump the year.
How many miles will a SGX last?
The median SGX shows 7,801 miles at test, and examples around 30k miles still pass 84.3% of the time — mileage alone rarely kills one.
