2017 Harley-Davidson Fat Boy®

/

Sometimes something comes along that changes everything.

When Willie G. Davidson rode the Fat Boy® model into Bike Week the first time, let’s just say it stopped traffic. No one had ever seen a factory custom motorcycle with this much visual impact before. The look was pure Harley, yet totally new. In the years since, the Fat Boy hasn’t let up. From the chrome of the solid disc wheels, to the muscular lines of the new High Output Twin Cam 103B™ engine to the curve of its distinctive rear fender, this machine is built to make an impact. Ride one and you’ll understand.

The original fat custom icon matches unmistakable style with a High Output Twin Cam 103B™ engine.

Authentic Styling

  • FAT CUSTOM STYLE: Recalling 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.
  • 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 Fat Boy® 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.
  • MIRROR CHROME WHEELS: These Mirror Chrome Bullet Hole Disc wheels speak for themselves. So this is the iconic look for the Fat Boy® model. You can roll with gleaming eye-appeal that'€™s thick with legendary Fat attitude, right off the lot.
  • 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.

Handling

  • 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.
  • FRONT BRAKE SYSTEM: The front brake system on the Softail® models delivers a 40 percent reduction in the amount of lever force required at peak braking. The handlebar master and front cylinders have been restyled. There's a 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.
  • ELECTRIC THROTTLE CONTROL: The pure heavyweight style of the Fat Boy® motorcycle gets even cleaner with the addition of electronic throttle control. Take a look. There'€™s no cable cluttering up the handlebars. Plus, the electronic set-up makes it a simple no-fuss-no-muss procedure to install Harley-Davidson® cruise control.

Iconic Engine

  • AIR COOLED, HIGH OUTPUT TWIN CAM 103B™: 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 High Output Twin Cam 103B™ 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 High Output Twin Cam 88® and High Output 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.
  • PURE HARLEY-DAVIDSON STYLING: Feast your eyes on the High Output Twin Cam 103B™ 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 High Output Twin Cam 103B™ engine makes an ironclad statement about holding on to what's right and staying true to what satisfies.
  • HIGH OUTPUT TWIN CAM 103B™ ENGINE POWER: Asking riders if they'€™d like more power is like asking them "€œWould you like more beer in the pitcher?"€ when they've reached the end of a long day tearing up the roads. Everybody wants it, and the High Output Twin Cam 103B™ engine is 103 cubic inches of Harley-Davidson V-Twin you can rely on to deliver it. The airbox increases intake airflow and the cam optimizes phase and duration. The result: better low-end torque and faster 60 to 80 mph 5th gear roll-on to get you around that 18-wheeler. In other words, it gets you motivated in a hurry. In the tradition of the legendary Harley iron that came before it, the High Output Twin Cam 103B™ engine is once again raising the bar for the feeling an engine delivers to the rider. There'€™s a reason we're called the Harley-Davidson Motor Company. Once you send some fuel to this engine, you'€™ll have no doubt whose it is.
  • IGH OUTPUT TWIN CAM 103B™ ENGINE INNOVATION: Fire up the High Output Twin Cam 103B™ 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 6-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 that couldn't feel better.
  • 6-SPEED CRUISE DRIVE® TRANSMISSION: You want a ride that rumbles—not begs for mercy—when you lean on it a little. The 6-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.
