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 XP's first-time pass rate has risen 4.1 points since 2017, 89.2% to 93.3%.
Pass rate by mileage
A low-mileage XP passes first time 94.1% of the time; by 30k that's 86.7%.
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 XP beats 4 of its 4 closest rivals (KAWASAKI ZX-6R, SUZUKI GSF600, YAMAHA FZS600).
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 XP.

Pass rate by registration year
Highest pass rate: 2016 (93.9%). Lowest: 2015 (90.2%). Every XP 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 XP FAQ
Is the YAMAHA XP reliable?
The YAMAHA XP is more reliable than average for its class: 92.2% of its 1,048 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #434 of 5428 models.
What does a XP fail its MOT on most?
brakes: 28% of all defects recorded against failed XP tests.
What is the best year of XP to buy used?
By first-time pass rate, 2016-registered examples do best (93.9%) and 2015 worst (90.2%). Condition and history still trump the year.
How many miles will a XP last?
The median XP shows 10,170 miles at test, and examples around 30k miles still pass 86.7% of the time, so mileage alone rarely decides the result.
