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 250 EXC's first-time pass rate has risen 9.8 points since 2006, 73.9% to 83.7%.

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 250 EXC beats 0 of its 4 closest rivals (YAMAHA YP250, YAMAHA WR250F, HONDA XR250).
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 250 EXC.

Pass rate by registration year
Best year to buy used: 2008 (78.6% pass). Weakest: 2000 (68.8%).
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.
KTM 250 EXC FAQ
Is the KTM 250 EXC reliable?

lighting and signalling — 34% of all defects recorded against failed 250 EXC tests.
What is the best year of 250 EXC to buy used?
By first-time pass rate, 2008-registered examples do best (78.6%) and 2000 worst (68.8%). Condition and history still trump the year.
