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.
