Data as of: DVSA MOT results to 2025
HONDA CG125BR
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 CG125BR's first-time pass rate has fallen 4.0 points since 2006, 71.6% to 67.6%.
Pass rate by mileage
A low-mileage CG125BR passes first time 78.7% of the time; by 40k that's 63.6%.
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 CG125BR beats 1 of its 4 closest rivals (YAMAHA YBR 125, HONDA CG125, HONDA CBF125).
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 CG125BR.

Pass rate by registration year
Highest pass rate: 1985 (76.2%). Lowest: 1988 (68.1%). Every CG125BR 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.
HONDA CG125BR FAQ
Is the HONDA CG125BR reliable?
The HONDA CG125BR is less reliable than average for its class: 70.9% of its 532 MOT tests (2005–2025) passed first time, against a class average of 73.4%. That ranks it #4671 of 5428 models.
What does a CG125BR fail its MOT on most?
lighting and signalling: 39% of all defects recorded against failed CG125BR tests.
What is the best year of CG125BR to buy used?
By first-time pass rate, 1985-registered examples do best (76.2%) and 1988 worst (68.1%). Condition and history still trump the year.
How many miles will a CG125BR last?
The median CG125BR shows 24,516 miles at test, and examples around 40k miles still pass 63.6% of the time, so mileage alone rarely decides the result.
