2006 Harley Davidson Fxdbi Dyna Street Bob
CarHunch analysed 193 real MOT records for the 2006 Harley Davidson Fxdbi Dyna Street Bob. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2006 Dyna Street Bob has a first-time pass rate of 67.1%, well below the UK average of 80%, which suggests these bikes need more attention to stay road-legal than typical vehicles. The good news is that dangerous defects are rare at just 5.7%, so you're not looking at safety nightmares—just the usual maintenance hassles that come with older Harleys.
At an average mileage of 13,076 miles for an 18-year-old machine, these bikes have been ridden gently, though that low mileage also means you should factor in age-related wear rather than assuming low miles equals low risk. The 0.64 average failures per vehicle and 2.7 advisories point to chronic issues like exhaust, lighting, and brake wear rather than catastrophic failures—so budget for regular servicing and get a pre-purchase inspection focused on those specific areas.
What to check before buying a 2006 Harley Davidson Fxdbi Dyna Street Bob
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.
