With its wide stance and fat styling, the Fat Bob® comes on like a back-alley brawler: big, bold and dripping with attitude. Muscled up forks, dual headlamps and a 16-inch front wheel wrapped in a 130mm tire give it a menacing, all-business stance and powerful performance.
The Fat Bob model proves there’s no such thing as too much black. From the aluminum triple clamps and battery box cover to the headlight trim ring and rear shock covers, this thick-cut, menacing bad boy is blacked out from top to bottom, nose to tail. Go ahead. Flash some black.
The Fat Bob® motorcycle features an internally wired 1 1/4-inch bar with tall risers. This beefy handlebar is truly reminiscent of an aggressive quarter mile monster. And with the wires routed through the steel, you get a clean, minimal look with nothing standing in your way of the open road.
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.
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.
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® and 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.
Easily adjust preload with a spanner wrench to suit your suspension to your riding style. The slammed low rear suspension gives you a more laid-back riding position and style. Low-profile, kicked back for profiling down the boulevard and hugging corners.
Keeping your mind clear and soaking up the freedom of the open road means not fretting about your ride. Especially when it comes to stopping. High performance, sleek design, the dual disc brakes feature 4-piston fixed calipers out front grabbing on floating rotors for superior stopping power.
