KTM 525 Exc Racing (2004)
2004 KTM 525 Exc Racing
CarHunch analysed 101 real MOT records for the 2004 KTM 525 Exc Racing. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 KTM 525 EXC Racing has a first-time MOT pass rate of just 61.3%, well below the UK average of 80%, which signals this is a challenging vehicle to keep roadworthy—though the dangerous defect rate of 5.9% isn't alarming by dirt-bike standards. Petrol two-stroke sportsters of this age demand meticulous maintenance to pass, and nearly four in ten don't make it on their first attempt.
With a median mileage of only 3,816 miles, these machines have covered relatively little ground for their age, yet owners still average 1.22 failures per test and 3.0 advisories, pointing to neglect or age-related deterioration rather than hard use. If you're considering one, budget for pre-MOT servicing—fresh plug, fuel system cleaning, and brake work—and expect to spend time at a specialist familiar with two-stroke cooling and carburettor tuning before test day.
What to check before buying a 2004 KTM 525 Exc Racing
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.
