vs expected · age & mileage

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.

SUZUKI TU250X FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI TU250X reliable?

The SUZUKI TU250X is about average for its class: 83.1% of its 3,107 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #2941 of 5428 models.

What does a TU250X fail its MOT on most?

brakes: 25% of all defects recorded against failed TU250X tests.

What is the best year of TU250X to buy used?

By first-time pass rate, 2000-registered examples do best (86.3%) and 1997 worst (80.3%). Condition and history still trump the year.

How many miles will a TU250X last?

The median TU250X shows 13,174 miles at test, and examples around 40k miles still pass 73.1% of the time, so mileage alone rarely decides the result.
