2010 Harley-Davidson Dyna Fat Bob

A Big Twin with big attitude, the Dyna® Fat Bob® leads with a brawny front end topped with dual head lights, rolls on chunky tires, and exits with a flip of its bobtail rear fender.

The Harley-Davidson® Dyna family has its roots in the factory-custom revolution of the 1970s, and combines Big Twin performance with an extended FX front end. Dyna models deliver great handling and bold styling.
