The legendary Fat Boy® motorcycle defined the "fat custom" category and imitators everywhere tried to copy its magic. This original continues to turn heads wherever it rolls, with fat tires, fat bars, a fat fender and a big, powerful, black powder-coated, counter-balanced Twin Cam 96B™ engine. The Fat Boy® model is the very definition of a heavyweight motorcycle, delivering a bold styling statement and a wide, comfortable riding stance. Now, for 2012, this boulevard icon offers a larger readout on the odometer with more information, such as gear and RPM data, plus the new Security Package option with an Anti-lock Braking System and Smart Security System. All this technology works seamlessly into the exquisite styling in a way that only Harley-Davidson can deliver.

AT CUSTOM STYLE

Hearkening to the 'hardtail' choppers of the '60s and '70s, the Fat Boy® 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, chrome 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.

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 rad, vintage-looking 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.

PREMIUM PAINT

Up to two times thicker than the competition, custom quality paint comes standard on all Harley-Davidson® motorcycles. Clearcoat layering up to five mils deep. Bigger metal flakes. Unique effects. Skimping simply is not in our vocabulary.

HAND FINISHED FUEL TANK

All Harley-Davidson® fuel tanks are finished by hand—that's what makes them stand out from the competition. Their seamless design and unmatched style are unique among all motorcycles on the road. The tanks are one of the first and last things people notice when they lay their eyes on a Harley-Davidson® motorcycle—so we make it worth their time.

FAT FEATURES

Big in all the right places. The 17-inch wheels of silver, bullet-hole, disc-cast aluminum definitely make an impression—especially with rubber 140mm wide in front and a beefy 200mm 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.

FAT CUSTOM TANK DETAILS

This tank makes a statement with its leather tank strap, chrome side badges, and chrome speedometer and ignition switch console. The speedo 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.

SIX-SPEED CRUISE DRIVE®

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.

TWIN CAM 103™ ENGINE POWER

New for 2012: live your ride to the power of 103. The air cooled Twin Cam 103™ Harley Davidson® engine delivers more stump pulling torque, while its Electronic Sequential Port Fuel Injection jetting gives crisp, lively throttle reaction. It’s a performance punch that you’ll appreciate when passing, climbing hills, or rolling with luggage packed or a passenger in back—all under that signature Motor Company rumble. And it comes at lower cruising rpm, so you ride more smoothly, with less engine vibration and better highway fuel economy.

TWIN CAM 103™ 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 the Twin Cam 103™; engine. We sweated bullets perfecting every cubic inch, pushing design and technology forward. And we did it all without compromising one bit of Harley-Davidson's unique styling. Evolved, yet carrying on the legacy of the Flathead, Knucklehead, Panhead, Shovelhead, Evolution®, Twin Cam 88®; and Twin Cam 96™ engines that came before. The performance and durability are a direct result of the untold miles logged on the V-Twin since 1909, and the proud heritage that comes from a century's worth of commitment to life on two wheels.

TWIN CAM 103™ ENGINE INNOVATION

Fire up the Twin Cam 103™ engine and feel the low-end torque unleashed. Thanks to the lightweight piston design, delivery of the added power is more refined than ever. Then put your foot on the shifter and feel how the engine and Six-Speed Cruise Drive® transmission were designed to work together. Six speeds. A strong driveline and strong internal parts. Low routine maintenance. And a low cruising rpm couldn't feel better.

PURE HARLEY-DAVIDSON STYLING

Feast your eyes on the Twin Cam 103™ engine and there's no mistaking its roots. This is authentic Harley-Davidson style through and through with an attention to detail you won't find from any other motorcycle company. Black powder-coated heads and cylinders are highlighted by machined cooling fin tips and chrome rocker covers. It's a jewel machined out of metal. Pure. Dripping with power. From the classic edge of the cooling fins to the clean lines of cases and covers—the Twin Cam 103™ engine makes an ironclad statement about holding on to what's right and staying true to what satisfies.

ANTI-LOCK BRAKES (OPTIONAL)

When it comes to the Fat Boy® model with optional ABS, 'stopping power' has a double meaning. The components of our ABS are tastefully hidden 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. Offered as a part of the 'Security Package' (which includes the H-D® Smart Security System).

H-D® SMART SECURITY SYSTEM (OPTIONAL)

The factory installed next-generation security system features a hands-free fob that automatically arms and disarms the vehicle 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 details and security that make Harley-Davidson® motorcycles unique. Offered as a part of the 'Security Package' (which includes Anti-Lock Brakes).

ARTFULLY HIDDEN TECHNOLOGY

Harley-Davidson leverages the latest in technology without compromising style and function. That means we hide electronics. The whole wiring harness is skillfully routed behind the jewels of the bike—the tank, engine and all the other eye-popping features you want to see. It's just another way The Motor Company goes the extra mile to give its bikes that premium, top-of-the-line fit and finish.

INTUITIVE CONTROLS

Hand controls on a Harley-Davidson® motorcycle are incredibly intuitive. The turn signals are self-canceling and, based on the speed and angle of the motorcycle, they know how long to stay on. Engaging the controls quickly becomes second nature so you can focus less on turning off your signal and more on basking in the freedom of the ride.

FAT DUNLOP® TIRES

Fatter is better. Rubber 140mm wide up front mitigates feedback from the street for a smoother ride. And the beefy 200mm 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.

TUNED TO BE RIDDEN

Harley-Davidson® motorcycles are different from any other bike out on the road. There's a balance to them. The steering, the maneuverability—it's all in concert. And each Harley-Davidson® model is tuned differently to create a unique riding experience for each individual no matter which bike they swing their leg over. Let's face it, we didn't get to where we are by being like everyone else.

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.

ENGINE IDLE TEMPERATURE MANAGEMENT STRATEGY

Our motorcycles are built to be ridden. A lot. So that means that rider comfort is top of mind. Always. With the Engine Idle Temperature Management Strategy (EITMS) feature, the motorcycle automatically cuts fuel and fire from rear cylinder when idling, which helps reduce engine heat felt by rider and passenger. This feature can easily be turned on by your dealer.

SEAT ENGINEERING AND DESIGN

The seat is home for Harley-Davidson® motorcycle riders. They want a seat that has unique style without sacrificing comfort. Because of that, Harley-Davidson invests a lot of time in researching, designing and testing seats so that every bike has just the right saddle.

CHROME LOW PROFILE HANDLEBARS

Practically begging you to reach out and grab your freedom, these low profile fat handlebars are the perfect place to start for both new riders and easy-rider comfort for road-hardened warriors. Newly designed for 2012, they offer reduced reach, giving you more comfort and better control of your cruise.

NARROW SEAT

To go along with the low seat height, we've added some ergos to make sure every inch of low pays off in pleasurable riding. We've slimmed up the seat itself. With the seat shape, lowdown frame and rigid powertrain, you can be sure you'll feel a solid, comfortable connection with the bike and road
