Fat Boy

The original fat custom icon that changed it all has done it again. Satin chrome finishes. Beefy 240mm rear tire. And now available in a Milwaukee-Eight® 107 or 114 Big Twin Engine for the most muscular, unstoppable Fat Boy® motorcycle ever.

Satin Chrome Finishes

An all-you-can eat portion of sculpted satin chrome gives the Fat Boy® a look that’ll make a big impact.

Steamroller Stance

A muscular look thanks to all-new solid-disc Lakester wheels wrapped in the widest front tire we’ve ever offered from the factory at 160mm combined with a 240mm rear tire.

Milwaukee-Eight® Big Twin Engine

A powerful, smooth-running engine with crisp throttle response and a pure, soul-satisfying rumble. Available in 107 and 114 engine displacements.

Signature LED Forward Lighting

Darkness-defying lighting that gives you greater visibility at night.

All-New Softail® Frame

A lighter, stiffer frame (compared to the prior Softail® and Dyna® models) that takes the idea of form and function to a place it’s never been before. It’s the look of a hard tail from a bygone era that delivers a thoroughly modern ride.

High Performance Front Suspension

New suspension technology provides the performance of a racing-style cartridge fork for reduced weight with linear damping characteristics.

High Performance Rear Mono Shock

All-new easily adjustable mono-shock rear suspension allows for dynamic cornering capability while preserving the hardtail look.
