Harley Davidson Fxdb Street Bob (2006)
2006 Harley Davidson Fxdb Street Bob
CarHunch analysed 103 real MOT records for the 2006 Harley Davidson Fxdb Street Bob. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2006 Harley-Davidson FXDB Street Bob has a first-time MOT pass rate of 66.1%, which is significantly below the UK average of 80%, suggesting these bikes need more maintenance attention than typical vehicles. The good news is that only 6.8% have ever recorded a dangerous defect, so safety-critical failures aren't widespread—but the below-average pass rate does signal reliability concerns worth taking seriously.
At an average mileage of 14,244 miles for an 18-year-old bike, these Street Bobs have relatively modest use, yet they're still averaging 0.77 failures per test, which indicates age-related wear rather than hard riding. Before committing to one, get a pre-purchase inspection focused on suspension, brakes, and electrical systems—the 3.4 advisories per vehicle average shows these components are where problems cluster on this model.
What to check before buying a 2006 Harley Davidson Fxdb 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.
