Wide tires front and back. Classic Lakester cast aluminum wheels. The iconic steamroller stance, backed by a Milwaukee-Eight® 117 motor. LED lighting all around, Rider Safety Enhancements standard, and fine factory details that honor one of Harley-Davidson’s most legendary silhouettes. The 2026 Fat Boy is bold by design.
