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 TTR's first-time pass rate has risen 5.0 points since 2006, 75.0% to 80.0%.
Pass rate by mileage
A low-mileage TTR passes first time 81.9% of the time; by 30k that's 75.3%.
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 TTR beats 2 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 TTR.

Pass rate by registration year
Highest pass rate: 2001 (87.3%). Lowest: 1993 (72.9%). Every TTR 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 TTR FAQ
Is the YAMAHA TTR reliable?
The YAMAHA TTR is less reliable than average for its class: 80.5% of its 1,254 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3478 of 5428 models.
What does a TTR fail its MOT on most?
steering and suspension: 26% of all defects recorded against failed TTR tests.
What is the best year of TTR to buy used?
By first-time pass rate, 2001-registered examples do best (87.3%) and 1993 worst (72.9%). Condition and history still trump the year.
How many miles will a TTR last?
The median TTR shows 10,393 miles at test, and examples around 30k miles still pass 75.3% of the time, so mileage alone rarely decides the result.
