MILWAUKEE (August 23, 2016) – More power. More comfort. More control. Today, Harley- Davidson redefined touring by unveiling the all-new Milwaukee-EightTM engine, the ninth Big Twin in its history, plus all-new front and rear suspension for its Model Year 2017 Touring motorcycle lineup.
“These are the most powerful, most responsive and most comfortable Touring motorcycles ever offered by Harley-Davidson,” said Scott Miller, Vice-President of Styling and Product Development Strategy. “The unmistakable look, sound and feel of Harley-Davidson Touring motorcycles rise to even greater heights with the improvements we’ve made this year. You truly have to ride it to feel it – so we’re inviting all riders to go to their local dealer and take a test ride.”
New Milwaukee-Eight Engine
The new Milwaukee-Eight engine, the ninth Big Twin design in the company’s storied lineage, is a clean-sheet design that combines the classic look, sound and feel of Harley-Davidson Big Twin engines with improvements in every aspect of engine performance.
“The Milwaukee-Eight engine carries the legacy of Harley-Davidson Big Twins into the future,” said Chief Powertrain Engineer Alex Bozmoski. “While respecting the essential Big Twin character, we’ve created an all-new motor. Every aspect of performance, durability and styling has been improved as a direct response to the voice of Harley-Davidson customers around the world.”
Retaining the classic 45-degree V-Twin cylinder angle, the Milwaukee-Eight engine produces 10 percent more torque than previous year models and features four-valve cylinder heads that offer 50 percent more intake and exhaust flow capacity. The Milwaukee-Eight engine is counter- balanced to cancel 75 percent of primary vibration at idle, retaining the classic feel of a Harley® V-Twin while being very smooth at highway speeds. A new heat management strategy for all Milwaukee-Eight engines improves rider and passenger comfort.
Milwaukee-Eight engines are offered in two displacements: the Milwaukee-Eight 107 (107 CID/1750cc) and Twin-CooledTM Milwaukee-Eight 107 (107 CID/1750cc) for standard motorcycle models and the Twin-CooledTM Milwaukee-Eight 114 (114 CID/1870cc) for Harley- Davidson® Custom Vehicle Operations (CVO)TM motorcycle models.
New Touring Suspension
All-new front and rear suspension components enhance the comfort, control and performance of all 2017 Harley-Davidson® Touring model motorcycles. New emulsion-technology rear shock absorbers offer 15 to 30 percent more pre-load adjustment than previous standard Touring shocks, with a single knob to hydraulically adjust pre-load.
“Pre-load can now be adjusted to match the load of rider, passenger and gear without tools or an air pump,” said Paul James, Harley-Davidson Director of Motorcycle Product Planning. “Once set, the pre-load will not leak down or require further adjustment.”
The front suspension features new Showa® SDBVTM suspension technology that delivers the damping performance of a racing-style cartridge fork with linear damping characteristics and reduced weight.
Screamin’ Eagle® Performance
Harley-Davidson Screamin’ Eagle® Performance will offer a full selection of street-legal performance components for the Milwaukee-Eight engines, including Screamin’ Eagle® Milwaukee-EightTM Stage I, II and III kits that deliver up to a 24 percent increase in torque over the stock engine.
Harley-Davidson Custom Vehicle Operations
Harley-Davidson® Custom Vehicle OperationsTM (CVO) models combine prestige and performance in three limited-edition factory-custom motorcycles for 2017.
- ď‚· Â The 2017 CVOTM Limited model is enhanced by the refined performance of the new Twin-Cooled Milwaukee-Eight 114 engine and improved ride and handling provided by the new suspension.

ALL-NEW HARLEY-DAVIDSON MILWAUKEE-EIGHT ENGINE POWERS REIMAGINED TOURING MOTORCYCLE EXPERIENCE
Newest Harley Big Twin Delivers More Performance and Comfort
MILWAUKEE (August 23, 2016) – The all-new Harley-Davidson® Milwaukee-EightTM engine, ninth in the lineage of the company’s iconic Big Twin engines, delivers more power and an improved motorcycling experience for riders and passengers while retaining the iconic look, sound and feel of its predecessors. An all-new design, the Milwaukee-Eight engine offers quicker throttle response, more passing power, purer sound, a smoother ride and more of the feeling riders want from a Harley-Davidson Touring motorcycle engine.
“The guiding principle behind the Milwaukee-Eight engine was our voice of customer research from every region of the world,” said Scott Miller, Harley-Davidson Vice-President of Styling and Product Development Strategy. “Riders asked us to create a new engine designed to enhance their motorcycle touring experience in every way. Those same voices also demanded that we stay true to our legacy and respect the defining elements of a Harley-Davidson V-Twin. It was a big challenge, but one we’ve met. With the Milwaukee-Eight, a new era of Harley-Davidson power, performance and innovation has been forged.”
New Milwaukee-Eight engines will power every 2017 Harley-Davidson Touring and Trike motorcycle model. Milwaukee-Eight engines will be offered in two displacements and three variations:
Milwaukee-Eight 107 (107 CID, 1750cc) featuring precision oil-cooled cylinder heads for the Street Glide®/Street Glide® Special, Road Glide®/Road Glide Special®, Electra Glide® Ultra Classic®, Road King® and Freewheeler® models.
Twin-CooledTM Milwaukee-Eight 107 (107 CID, 1750cc) featuring liquid-cooled cylinder heads for the Ultra Limited/Ultra Limited Low, Road Glide® Ultra and Tri Glide® Ultra models.
Twin-Cooled Milwaukee-Eight 114 (114 CID,1870cc) featuring liquid-cooled cylinder heads for the CVOTM Limited and CVOTM Street Glide® models.
More Power
Each Milwaukee-Eight engine produces 10 percent more torque than the engine it replaces in Touring models. In addition to increased displacement, the Milwaukee-Eight engine features a higher compression ratio and four-valve cylinder heads with 50 percent more intake and exhaust flow capacity. The valve train requires no adjustment as the design of the rocker arms enables valve lash to be set at the factory for life. Dual spark plugs for each cylinder contribute to more- efficient combustion. A single chain-driven camshaft is lighter, mechanically less complex and creates less friction and noise.
“The Milwaukee-Eight engine retains the classic Harley-Davidson 45-degree V-Twin design,” said Alex Bozmoski, Harley-Davidson Chief Powertrain Engineer, who led the development team. “It also retains the power characteristic that is the real legacy of the Harley-Davidson Big Twin: strong low-end torque with a broad, flat power curve through the mid-range that’s ideal for the Touring motorcycle rider.”
Quicker Acceleration
The Milwaukee-Eight engine weighs the same as the engines it replaces, so all of its extra power contributes directly to improved acceleration performance.
- ď‚· Â The Milwaukee-Eight 107 accelerates 11 percent quicker 0-60 mph, equal to a two to three bike length improvement, and 11 percent quicker from 60-80 mph in top gear, equal to a one to two bike length improvement, compared to the Twin Cam High Output 103.
- ď‚· Â The Milwaukee-Eight 114 accelerates 8 percent quicker 0-60 and 12 percent quicker 60- 80 than the Twin Cam 110TM.Heat Management
The Milwaukee-Eight engine offers improved rider and passenger thermal comfort due to reduced heat absorption, increased heat rejection and a redesigned exhaust system. Each Milwaukee-Eight engine features a precision cooling strategy based on the specific demands of the motorcycle model, using a targeted flow of either oil or liquid coolant around the hottest areas of the cylinder heads. A new knock sensor for each cylinder enables more-precise timing control. The rear exhaust pipe is re-positioned and the exhaust catalyst is relocated to move heat away from the passenger. Idle speed is lowered from 1,000 rpm to 850 rpm.
Improved Fit
A new, slimmer primary drive cover and the low-profile shape of the air cleaner cover provide improved rider legroom around the engine and an easier reach to the ground for many riders. All Milwaukee-Eight powered models are fitted with an Assist and Slip Clutch with improved hydraulic actuation that reduces clutch lever effort by 7 percent.
Reduced Vibration
The rubber-mounted Milwaukee-Eight engine features a single internal counter balancer that
cancels 75 percent of primary vibration at idle for a more-refined feel and more-comfortable experience for rider and passengers while retaining the classic character of Harley® V-Twin engines.
Richer Exhaust Note
Lighter valves, a single camshaft, optimized cover designs and improved driveline components eliminate mechanical powertrain noise. The engine intake and air cleaner are designed to reduce intake sound while ensuring maximum air flow. As a result, the new Milwaukee-Eight engine is mechanically quieter, enabling a richer exhaust tone, and meets all global noise and emissions standards while allowing the unmistakable rumble of its exhaust note to resonate.
Improved Charging
The Milwaukee-Eight engine charging system delivers 50 percent more output to the battery at idle to better support the power demands of Touring riders, including accessory lighting, performance audio, and heated gear and other accessories.
New Engine Styling
The Milwaukee-Eight engine features sleek, modern styling that respects the heritage of previous Harley-Davidson Big Twin engines.
“The Milwaukee-Eight engine is styled to project power,” said Brad Richards, Harley-Davidson Director of Styling. “I compare it to the back of a swimmer, lean in the waist but broad and muscular in the shoulders.”
“The rocker covers look like skin stretched taut over muscle, like the rocker arms are about to burst out of the engine,” said Richards. “For the first time since the Knucklehead, the rocker covers reflect the action going on below. And they are massive. When you sit on the bike you can look down and see more of this engine.”
