Pass rate over time
The SAXON's first-time pass rate has risen 3.3 points since 2006, 86.7% to 90.0%.
Pass rate by mileage
A low-mileage SAXON passes first time 89.5% of the time; by 50k that's 80.3%.
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 SAXON beats 3 of its 4 closest rivals (YAMAHA RD350, YAMAHA YP250, YAMAHA WR250F).
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 SAXON.
Pass rate by registration year
Best year to buy used: 1996 (86.3% pass). Weakest: 1995 (83.2%).
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.
MZ SAXON FAQ
Is the MZ SAXON reliable?
The MZ SAXON is about average for its class: 84.7% of its 601 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #2572 of 5426 models.
What does a SAXON fail its MOT on most?
lighting and signalling — 36% of all defects recorded against failed SAXON tests.
What is the best year of SAXON to buy used?
By first-time pass rate, 1996-registered examples do best (86.3%) and 1995 worst (83.2%). Condition and history still trump the year.
How many miles will a SAXON last?
The median SAXON shows 36,407 miles at test, and examples around 50k miles still pass 80.3% of the time — mileage alone rarely kills one.
