The 2017 Forty-Eight® motorcycle comes at you with more low-slung Dark Custom attitude than ever, from its fat front end to its cast aluminum wheels.

Classic Peanut Fuel Tank with Badge

First appearing on a Harley-Davidson® motorcycle back in 1948—and providing the inspiration for the Forty-Eight® model name—the small 2.1 gallon tapered peanut fuel tank holds strong today with its traditional styling and modern attitude. It adds to the machine's low, powerful bulldog look, showing off the solid mass of the engine and the rawboned style of the lean Sportster® frame. We mount it on a metal strip drilled with old-school “lightening” holes. Then top the works with vivid graphics and a 3D metal badge rooted deep in the bike’s retro modern culture. The peanut fuel tank is attitude and looks all balled up into one.

Fat Front Wheel

A beefy front end with a tall, fat MT90 tire gives the Forty-Eight® model a grounding visual equal to that of a 1950 Mercury. Custom rubber reminiscent of the lead-sled culture. A dominating presence up front that provides a smooth ride and solid handling.

Hard Candy Custom Paint

Hard Candy Custom paint is a large metal flake finish that’s more than just paint job, it’s a shining declaration of independence—bright, bold and unique. The Sportster® model Forty-Eight® is available in Hard Candy Custom Black Gold Flake and Hot Rod Red Flake. Recalling the iconic rebel styling of ‘70s custom bikes, Hard Candy Custom paint marks another milestone in The Motor Company’s legacy of innovation. We start with several passes of 200 micron flake over a black base, then clear coat it, hand-lay the graphics, and apply the many layers of clear coat to allow the flake to shine through. It’s a painstaking process that delivers a premium custom look straight from the factory, so you can start flying your colors with no waiting or extra effort.

Slammed Handlebar, Speedo and Under Mount Mirrors

The slammed black drag-style handlebar with speedo and under mount mirrors adds to the stripped down, minimal look of the Forty-Eight® motorcycle. Inspired by the way hot rod pioneers used to slam their rides, the drag style handlebar is an old-school garage feature that demands a forward, aggressive riding position.

Exhaust with Laser Cut Exhaust Shields

The staggered shorty-dual exhaust has been around almost as long as the Sportster® family itself. But that doesn’t mean we can’t take the time-honored pipes to a place that’s brand new. To achieve the stunning dark-breaking-through-bright look on the Forty-Eight® exhaust, we blacked-out the mufflers. Then topped them with chrome exhaust shields adorned with laser-cut groves.

Pure Harley-Davidson Styling

Feast your eyes on the 1200cc Evolution® 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. Right in the center: a round air cleaner cover, covered in gloss black and loaded with retro style. Surrounding it you have black powder coating on the cases and cylinders, polished rocker covers, and a final touch of chrome pushrods to highlight the iconic V-Twin shape. It's a jewel machined out of metal. Pure. Dripping with power. The 1200cc Evolution® engine makes an ironclad statement about holding on to what's right and staying true to what satisfies the rider.

Tach and Gear Indicator Readout

Even though none of us would want to admit it, from time to time, we've all had to kick our shift lever back down to 1 to figure out what gear we were in. The Sportster® models get a speedometer with a gear indicator readout and a tachometer you can activate with your trip switch. Now you've got all the information you need to keep it in the power band at the touch of a finger.

Closed Loop Exhaust System

Designed to meet future worldwide emissions standards and the standards of future generations of Harley-Davidson® motorcycle riders. This closed loop exhaust system delivers heart-pounding performance in the key of the trademark Harley-Davidson rumble. With its robust, soul-stirring big twin design, durable mufflers with exhaust shields, a catalyst and mini heated oxygen sensors that improve emissions and drivability, this system is not only better for the environment, it makes riding better.

Foundation Brake System

Like riding itself, you can never go too far when it comes to a bike’s brakes. This is why we went the distance to make the brake system of each Sportster® model a shining example of performance, fit and finish. You have 300mm brake rotors and a powerful, stylized front caliper with 34mm pistons and stylized rear caliper to match. Other system features include an improved all-aluminum integrated rear master cylinder with reservoir, all-aluminum front master cylinder with reduced friction and higher efficiency, and stainless steel braided lines. It all adds up to more confidence on the road and more power and predictability when you squeeze the brakes.

Michelin ® Scorcher Tires

Michelin® Scorcher tires provide the superior performance, sensational grip, impressive durability and excellent handling expected on a race-bred bike. The exclusive deep-cut tread design improves grip and water evacuation capability. Grip performance and durability is also enhanced by the tire's rubber compounds, which use the latest generation of Michelin synthetic polymers.

49mm Fork with Cartridge Dampening

The front end of the Forty-Eight® motorcycle comes at you like a left hook from a bareknuckle boxer, loaded with raw power and bruising style. The eye starts at the big balloon front tire, then immediately lands on the brawny 49mm front fork, accentuated by massive triple clamps and fork brace. There’s nothing else like it on the street. The one thing that isn’t rough and tumble is the way it all feels. We’ve been busy upgrading the ride of every Sportster® model, adding cartridge dampening technology to that brawny front fork. It keeps the handling crisp and confident, no matter how rough or winding the road ahead.

Split 9-Spoke Cast Aluminum Wheels

The plentitude of fat black rubber rolling underneath the Forty-Eight® motorcycle calls for a set of equally hardcore rims, so we came up with a special split 9-Spoke design, covered it all in black, then added machined highlights to set off the design. The belt sprocket and floating front brake rotor get a similar treatment for good measure. The wheels are lightweight cast aluminum, so even with all that rubber the ride feels light and nimble.

Emulsion Rear Shock with Screw Adjuster

The urban infrastructure isn’t getting any smoother, so we upgraded the rear suspension throughout the Sportster® family. We went with an Emulsion rear shock with a screw pre-load adjuster. It not only works overtime to soak up every bump the street throws your way, it also adjusts to fit your riding style. Simply use the tool mounted under the seat to turn the screw and you have a rear suspension set up to ride as aggressively as you want to take it.
