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

same type, similar capacity, high test volume

On first-time pass rate the XR400R beats 2 of its 4 closest rivals (KAWASAKI ER5, SUZUKI GS500, SUZUKI AN400).

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 XR400R.

Pass rate by registration year

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 XR400R FAQ

answers computed from the data above · terms in the glossary

Is the HONDA XR400R reliable?

The HONDA XR400R is less reliable than average for its class: 77.8% of its 951 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #3940 of 5426 models.

What does a XR400R fail its MOT on most?

lighting and signalling — 38% of all defects recorded against failed XR400R tests.

What is the best year of XR400R to buy used?

By first-time pass rate, 1998-registered examples do best (84.8%) and 2002 worst (73.0%). Condition and history still trump the year.

How many miles will a XR400R last?

The median XR400R shows 6,953 miles at test, and examples around 20k miles still pass 85.2% of the time — mileage alone rarely kills one.
