2018 Harley-Davidson® Fat Boy® - Color Option
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.
- 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.
- 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.
- Signature LED Forward Lighting: Darkness-defying lighting that give 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 Showa® SDBV® 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.
