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 XF650 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI XF650 reliable?

The SUZUKI XF650 is less reliable than average for its class: 80.9% of its 3,408 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3398 of 5428 models.

What does a XF650 fail its MOT on most?

brakes: 30% of all defects recorded against failed XF650 tests.

What is the best year of XF650 to buy used?

By first-time pass rate, 2002-registered examples do best (88.6%) and 1998 worst (77.6%). Condition and history still trump the year.

How many miles will a XF650 last?

The median XF650 shows 22,542 miles at test, and examples around 50k miles still pass 73.8% of the time, so mileage alone rarely decides the result.
