Key Features

AUTHENTIC STYLING

Fat Custom Style

Fat Boy® Lo

Hearkening to the "hardtail" choppers of the '60s and '70s, the Fat Boy® Lo model keeps that heritage alive more than forty years later. And this special edition shows a darker side of the original "fat custom" bike—laid-back and blacked-out with an unmistakable profile on the road.
But the nostalgic style isn't just about the confident stance, paint and old-school detail. It's how you look riding it. It's how it feels. It's the classic, relaxed riding position that speaks volumes. You're not just cruising. You're in charge—kicked back on a throne of machined metal surveying your domain.

Fat Features

Fat Boy® Lo

Big in all the right places. The 17-inch wheels of black, 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. 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.

Blacked Out Finishes

Fat Boy® Lo

You might say black is the new chrome when it comes to the Fat Boy® Lo model. There's black denim finish on the frame, swingarm, front shock covers, derby cover, horn cover, coil cover, oil tank and air cleaner cover. Black, bullet-hole disc-cast aluminum wheels with black centers and matching outer rims. Flat-black exhaust shields on the chrome shotgun exhaust. Gloss black half-moon footboards. Even blacked-out mirrors and headlamp. And black powder-coating on the powertrain with satin chrome accents finishes the job. With all this paint, you won't just be riding fat and low. You'll be throwing shade all the way.

Hidden Rear Shocks

Fat Boy® Lo

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.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Tank-Mounted Console

Fat Boy® Lo

For 2011, the speedometer face boasts an even bigger, bolder display for the odometer and offers up more information on the fly, like an ancillary display for gear and rpm.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Premium Paint

Fat Boy® Lo

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

Fat Boy® Lo

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.

ICONIC ENGINE

Twin Cam 96B™ Engine Heritage

Fat Boy® Lo

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 96B™ counter-balanced 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® and Twin Cam 88® 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.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Twin Cam 96B™ Engine Innovation

Fat Boy® Lo

Fire up the air-cooled, rigid-mounted Twin Cam 96B™ counter-balanced engine and feel the low-end torque unleashed for a smooth ride. 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.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Pure Harley-Davidson Styling

Fat Boy® Lo

Feast your eyes on the Twin Cam 96B™ counter-balanced 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 on any other bike.
The black powder-coated engine with machined cooling fin tips and satin chrome accents is topped off with brilliant chrome rocker covers. Rigid-mounted and air-cooled, the 1584cc Twin Cam 96B™ engine provides increased power, smooth performance and a maintenance-free built-in primary auto chain tensioner. 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 96B™ engine makes an ironclad statement to holding on to what's right and staying true to what satisfies the rider.

Six-Speed Cruise Drive®

Fat Boy® Lo

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.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Classic Harley-Davidson Rumble

Fat Boy® Lo

Iconic, fierce, the most distinct decibels you'll ever hear bouncing off the city canyons or scenic country landscapes. The sound of a Harley-Davidson® motorcycle has a rich history of its own. It's a classic roar. It's the sound of freedom, soul and self-expression.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

TECHNOLOGY

Anti-Lock Brakes (Optional)

Fat Boy® Lo

When it comes to the Fat Boy® Lo 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).

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

H-D® Smart Security System (Optional)

Fat Boy® Lo

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).

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Artfully Hidden Technology

Fat Boy® Lo

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

Fat Boy® Lo

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.

HANDLING

Low Suspension

Fat Boy® Lo

To give the Fat Boy® Lo model its distinctive road-hugging stance, we've dropped the front and rear suspension 1.15 inches. That makes it the lowest seat height of any stock Harley-Davidson® model at a down and dirty 24.25 inches. Perfect for smaller riders or those who just like to feel down in the bike.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Fat Dunlop® Tires

Fat Boy® Lo

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 since they're from Dunlop®, you know you're wrapping your premium rollers in quality rubber.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Tuned to Be Ridden

Fat Boy® Lo

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.

COMFORT

Full-Length Rider Footboards

Fat Boy® Lo

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.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Narrow Seat

Fat Boy® Lo

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.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Engine Idle Temperature Management Strategy

Fat Boy® Lo

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.

Vehicle shown may vary visually by market.  Vehicles depicted may differ from vehicles manufactured and delivered.  See your dealer for details.

Seat Engineering and Design

Fat Boy® Lo

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.
