Yamaha Wr 450 F (2004)
2004 Yamaha Wr 450 F
CarHunch analysed 131 real MOT records for the 2004 Yamaha Wr 450 F. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 Yamaha WR 450F passes its MOT first time just 63.6% of the time, well below the UK average of 80%, which suggests these bikes need closer pre-test attention than most vehicles. The good news is that dangerous defects are relatively uncommon at 12.2%, so when failures do occur they're typically manageable issues rather than safety-critical problems.
These are low-mileage machines with a median of only 2,223 miles, indicating they're often kept as weekend or off-road bikes rather than daily runners, which explains why advisories average four per vehicle despite relatively light use. Before buying one, budget for a professional pre-MOT inspection focusing on the electrical and brake systems, as the 1.38 average failures per vehicle suggests these are the likely culprits on aging examples.
What to check before buying a 2004 Yamaha Wr 450 F
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
