2008 FLSTF/FLSTFI Fat Boy
 

 


One of the most recognizable motorcycles on the road, the FLSTF Fat Boy defines Harley-Davidson for many people. Still going strong after 18 years and as massive as it is iconic, the Fat Boy rolls on a 200 mm rear tire and chopped FL rear fender. Laced leather and bullet studs trim the two-up seat and tank strap. A big 17-inch front wheel and bright chrome fork nacelle lead the way. Bullet Hole Disc Aluminum wheels identify this Softail as the one and only Fat Boy.
