The 2003 Yamaha WR450F passes its MOT first time 82.8% of the time, which is marginally better than the UK average of 80%, and only 10% of these bikes have ever recorded a dangerous defect—a reassuringly low figure. This is a specialist off-road machine, and the median mileage of just 1,865 miles suggests most surviving examples are weekend riders rather than hard-worked commuters, which explains the solid pass rate despite their age.

When these bikes do fail MOT, they average 1.42 failures per vehicle and 4.4 advisories, indicating minor wear issues rather than systemic problems. If you're considering one, inspect the service history carefully and budget for addressing any advisories promptly, since the low typical mileage means neglect rather than wear is usually the culprit.

We have limited data for the 2003 Yamaha Wr450f — treat the figures below as indicative rather than definitive.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
