Standard Features

 Power Blackout. This takes dark to a new level. A powerful one. New gloss black Screamin’ Eagle® air-cooled Twin Cam 110B™ engine, gloss black lower forks, axle nut covers, handlebar and riser. Black brake lever and hydraulic clutch assembly. Black over / under shotgun exhaust with slash cut mufflers. Take our word for it, it is blacked-out from front to back and head to toe in attitude.  
Authentic Styling
 Dark Design: When we say the Fat Boy® S model is dark, we mean black. Johnny Cash wardrobe black. Ace of spades black. Aside from the chrome rims, tank graphics and a few other assorted highlights, this machine is covered wheel to wheel in finishes as dark as midnight. The front console is gloss black; the brake levers, hydraulic clutch assemblies, handlebar, handlebar riser and triple clamp are black. The headlamp trim ring is black. Even the axle nut covers are black. The paint comes in two choices: Vivid Black and Denim Black. If you want to ride the dark horse, this is as dark as it gets.  
 Blacked-Out Exhaust: The gloss black 110 cubic inch counter-balanced V-twin engine on the Fat Boy S model feeds its sound to the world through 2-into-2 exhaust with blacked-out pipes and mufflers.  
 Fat Features: Big in all the right places. The 17-inch wheels of black bullet-hole, die-cast aluminum with silver rims definitely make an impression – especially with rubber 140 mm wide in front and a beefy 200 mm in back. And check out the chopsticks up front – fat front fork behind the huge, gorgeous headlamp. The handlebars are wide, giant stainless steel with bare-knuckle chrome risers. Plus, the fuel tank medallion boasts a generous slab of mirror chrome finish – noticeable on any stretch of road. It's a lot of fat in one tight bike. Definitely meaty. Wide. Big-boned. A bruiser. Call it what you want. Just admit that you want it.  
 Black Bullet-Hole Disc Wheels: These black bullet-hole disc wheels speak for themselves. So this is the iconic look for the Fat Boy model. You can roll with eye-appeal that’s thick with legendary Fat attitude, right off the lot.  
 Fat Custom Style: Recalling the "hardtail" choppers of the '60s and '70s, the Fat Boy S motorcycle keeps that heritage alive more than forty years later. This is the original "fat custom" bike – laid-back and luxurious with an unmistakable profile on the road. But the nostalgic style isn't just about the confident stance, and old-school detail. It's how you look riding it. It's how it feels. It's the classic, relaxed riding position. You're not just cruising. You're in charge – kicked back on a throne of machined metal surveying your domain.  
 Fat Custom Tank Details: This tank makes a statement with its leather tank strap, chrome side badges, and blacked-out ignition switch console. The Fat Boy S model speedometer face boasts a big, bold display for the odometer and an ancillary display for gear and RPM, so all the info you need on the fly is yours at a glance.  
 Hidden Rear Shocks: If you want a comfortable bike but love that rigid-suspension look, you've come to the right bike. We've kept all the modern comforts where they belong – below the surface of a dark, raw, hardcore custom bike. You get the classic lines of a vintage "hardtail" frame with the horizontal rear shocks hidden in the guts. It's a signature rigid look, and you'll only find it on a Softail® model.  
Iconic Engine
 Screamin' Eagle Ventilator Intake: Sitting between the big cylinders on the Fat Boy S model you'll notice a blacked-out Screamin' Eagle Ventilator Performance intake marked by Screamin' Eagle 110 graphic that leaves no doubt as the muscle powering this machine. It features a high flow filter that lets the engine gulp air in massive quantities in order to make massive amounts of power. One look is all you need to know this is no stock machine.  
 Screamin’ Eagle Air-cooled, Twin Cam 110B Engine Power: The Screamin’ Eagle air-cooled, Twin Cam 110B engine in the Fat Boy S model is built to deliver awesome power and a smooth ride at the same time. Counter balancers dampen the vibration while the big pistons pump out the torque. You get big power on the low end and plenty to keep you on the high end. There's a reason we're called The Motor Company. And once you send some fuel to this one, you'll know what it is.  
 Screamin’ Eagle Air-Cooled, Twin Cam 110B Engine Heritage: The knowledge of what makes an engine truly move a rider runs deep at The Motor Company, and it was put to good use when we created this counter-balanced Twin Cam 110 engine. We sweated bullets perfecting every cubic inch, pushing design and technology forward. And we did it all without compromising one bit of the unique Harley-Davidson® styling. Evolved, yet carrying on the legacy of the Flathead, Knucklehead, Panhead, Shovelhead, Evolution® and Twin Cam engines that came before. The performance and durability are a direct result of untold miles logged on the V-twin since 1909 and the proud heritage that comes from a century's commitment to life on two wheels.  
 Screamin’ Eagle Air-Cooled, Twin Cam 110B Engine Innovation: Fire up the counter-balance Twin Cam 110 engine and feel the low-end torque unleashed. The colossal 110 cubic inches provide seemingly endless torque with adrenaline-pumping pull through all six gears. And counter balancing keeps the engine rock solid smooth through all six gears. Six speeds, a strong driveline and a low cruising RPM couldn't feel better.  
 Screamin’ Eagle Air-cooled, Twin Cam 110B Engine Style: Pure. Dripping with power. A jewel machined out of metal. There's no mistaking the roots of the Twin Cam 110 engine with its Screamin' Eagle badges: authentic Harley-Davidson style through and through. Its gloss black heads sit atop cylinders with machined cooling fin tips to highlight the muscular shape of the engine. It's a pure, powerful declaration of the value of staying true to what satisfies the rider.  
 Six-Speed Cruise Drive® Transmission: You want a ride that rumbles – not begs for mercy – when you lean on it a little. The Six-Speed Cruise Drive transmission provides smooth, quiet shifting and reduces engine speed on the highway, so you get a better match between engine turnover and road speed. It's a rare ride when a bike responds like this, and a low growl goes a long way when you're opening up the road ahead.  
 H-D® Smart Security System: The factory-installed next-generation security system features a hands-free fob that automatically arms and disarms the vehicle's electronic security functions as you approach and walk away from the bike. Stick the fob on your ignition key ring and let it do all the work. It's this attention to detail and security that make Harley-Davidson motorcycles unique.  
 Anti-Lock Brakes: This sophisticated, factory-installed ABS gives "stopping power" a double meaning. You'll turn heads with clean, streamlined design. But more importantly, you get certainty in the saddle knowing your bike's going to behave when you need it.  
 Fat Dunlop® Tires: Fatter is better. Rubber 140 mm wide up front mitigates feedback from the street for a smoother ride. And the beefy 200 mm rear tire provides a confident feeling of sure contact with the road and excellent traction under braking. And since they're from Dunlop, you know you're wrapping your premium rollers in quality rubber.  
 Front Brake System: The front brake system on the Softail models this year delivers a 40% reduction in the amount of lever force required at peak braking. The handlebar master and front cylinders have been restyled. There's a new 4-piston fixed caliper with 32 and 34 mm pistons, premium caliper piston coating to minimize initial displacement and a larger 300 mm rotor. It all adds up to more stopping power with less effort.  
 New Ergonomically Designed Hand Controls: When you've put as many miles as we have in the saddle, you get a strong feel for what’s right and wrong on a motorcycle. Even the smallest annoyances start to add up with each passing mile, and that’s especially true of the way the handlebar feels in your grip. So we worked over the hand controls with as much passion as we worked over the engine powering the Fat Boy S motorcycle. The shapes feel good, and are angled to fall right under your thumbs. It’s just one more way each new mile feels even better than the ones that came before.  
 New Electronic Throttle Control and Cruise Control: The minimalist styling of the Fat Boy S motorcycle gets even cleaner with the addition of standard electronic throttle control. Take a look. There’s no cable cluttering up the handlebars. Cruise control is also included, standard. The switches are placed where you can easily dial in your speed with your left thumb. That’s all it takes to give your wrist a break and keep on hauling down the road.  
 Standard Anti-Lock Brakes: When it comes to the Fat Boy S model with ABS, "stopping power" has a double meaning. The components of our ABS are tastefully stylized within the wheel hub, so you'll still turn heads with clean, streamlined design. More importantly, though, you get certainty in the saddle knowing your bike's going to behave when you need it.  
 Low Profile Black Handlebars: These beefy 1-1/4 inch bars not only add to the overall Fat styling, with internally-routed wiring for a bold clean look, their ergonomic design and reduced-reach positioning provide comfort and confidence as you guide your ride whether you're heading across town or onward to the horizon.  
 Full-Length Rider Footboards: Your boots were made for riding, in any way you see fit. Our full-length footboards boast a tried and true design that's stood the test of time. Plenty of foot positions for your taste and comfort. Rubber vibration isolation for a comfortable ride. And heel-toe shifting for confident shifting every time. It takes a few rides, but once you've gotten used to the smooth heel-toe rhythm, you'll never give it up. The toes of your boots won't take the same beating, either.
