This 2007 Fat Boy is a serious reliability concern: only 11.3% pass first time against the UK average of 80%, and petrol versions are even worse at just 4.1%. With zero dangerous defects recorded across 120 vehicles, safety isn't the issue—it's simply that these bikes fail MOT repeatedly, suggesting systemic problems with emissions, lights, or chassis components that don't get properly fixed between tests.

The median mileage of 1,930 miles is remarkably low for a 17-year-old machine, indicating these are mostly collector bikes or seasonal riders, yet they still can't pass MOT cleanly. If you're considering one, budget for a pre-purchase inspection by a Harley specialist and expect to spend several hundred pounds getting it MOT-ready before you can legally ride it.
