Data as of: DVSA MOT results to 2025
The pass rate is the MOT first-time pass: a roadworthiness check of the items an MOT covers (brakes, lights, tyres, steering, structure, emissions), not a full mechanical inspection of engine or gearbox internals. It is a reliability signal, not a complete measure of mechanical reliability. What this measures.
“vs expected” adjusts for age, mileage and test class, so a cherished classic and a hard-used commuter are compared fairly. How this works.
Pass rate over time
The SRX's first-time pass rate has risen 7.0 points since 2006, 83.3% to 90.3%.
Pass rate by mileage
A low-mileage SRX passes first time 91.3% of the time; by 40k that's 80.9%.
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 SRX beats 3 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 SRX.

Pass rate by registration year
Highest pass rate: 1988 (88.7%). Lowest: 1986 (81.8%). Every SRX year compared →
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.
YAMAHA SRX FAQ
Is the YAMAHA SRX reliable?
The YAMAHA SRX is about average for its class: 83.8% of its 550 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #2791 of 5428 models.
What does a SRX fail its MOT on most?
lighting and signalling: 26% of all defects recorded against failed SRX tests.
What is the best year of SRX to buy used?
By first-time pass rate, 1988-registered examples do best (88.7%) and 1986 worst (81.8%). Condition and history still trump the year.
How many miles will a SRX last?
The median SRX shows 26,232 miles at test, and examples around 40k miles still pass 80.9% of the time, so mileage alone rarely decides the result.
