Should I check the MOT history before buying a 2004 Yamaha Wr450f?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

This 2004 WR450F passes its MOT slightly more often than the UK average, with an 83.2% first-time pass rate versus 80% nationally, and dangerous defects are uncommon at just 9.5% of vehicles ever flagged. However, the median Carhunch score of 50 suggests these bikes sit right at the middle of the reliability spectrum—not a standout performer.

Most examples have genuinely low mileage for their age, averaging just 3,414 miles, which means wear-related failures are less common than you'd expect from a 20-year-old machine. The real story lies in advisories: at nearly five per bike on average, these WR450Fs typically need attention to non-critical items like worn cables, minor corrosion, or aging rubber—standard maintenance for a dirt bike of this era. Before buying, budget for a pre-purchase inspection that specifically checks the suspension and plastics, as those advisory numbers suggest cosmetic and consumable parts take the brunt of age and use.

We have limited data for the 2004 Yamaha Wr450f — treat the figures below as indicative rather than definitive.
