Fat Boy®
In Brief
The look of the Fat Boy® is more muscular than ever, thanks to all-new solid-disc wheels, and the 240mm rear tyre matched with a 160mm front. But now the Fat Boy® is 29lb lighter and benefits from the extra power of the Milwaukee-Eight® V-Twin engine.
NEW FOR 2018
- The Milwaukee-Eight® 107 and 114 engines
- 34% stiffer chassis overall
- Reduced weight
- New Showa® SDBV® front suspension technology
- High-performance rear monoshock
