KTM 990 Adventure (2006)
2006 KTM 990 Adventure
CarHunch analysed 144 real MOT records for the 2006 KTM 990 Adventure. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2006 KTM 990 Adventure passes its MOT on the first attempt 83.4% of the time, slightly above the UK average of 80%, suggesting solid baseline reliability for a bike of this age. The dangerous defect rate sits at a manageable 11.8%, well below the warning threshold, so structural and safety issues are relatively uncommon.
These machines show modest mileage wear—averaging 22,717 miles across the sample—which is reasonable for a 18-year-old adventure bike, though you'll see quite a spread. Typical failures number just over one per vehicle with 3.2 advisories per bike, pointing to routine wear items rather than systemic problems; before buying, check the service history closely and have a pre-purchase inspection focus on suspension components and fuel system condition, both common weak points on this model.
What to check before buying a 2006 KTM 990 Adventure
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.
