The 2020 Harley-Davidson Fat Boy's 78.9% first-time pass rate sits just slightly below the UK average of 80%, suggesting fairly typical reliability for the model—nothing to worry about, but nothing exceptional either. Only 7.7% of these bikes have ever shown a dangerous defect, which is comfortably low and indicates no systemic safety issue.

At just over 5,000 miles on average, these Fat Boys are lightly used for their age, which explains the minimal failure rate of 0.18 per vehicle. The 0.8 advisories per bike suggest minor wear items crop up occasionally, so factor in routine maintenance costs when budgeting; a pre-purchase inspection should focus on brake fluid condition and exhaust system corrosion, the typical culprits on older Harleys in this mileage band.
