More power. More comfort. More control. Harley-Davidson redefined touring by unveiling the all-new Milwaukee-Eight engine, plus all-new front and rear suspension for its Model Year 2017 Touring motorcycle lineup.
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, 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, better fuel economy, a smoother ride and more of the feeling riders want from a Harley-Davidson Touring motorcycle engine.
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, 1745cc featuring precision oil-cooled cylinder heads for the Street Glide Special, Road Glide Special, Road King/Road King Classic and Freewheeler models.
Twin-Cooled Milwaukee-Eight 107, 1745cc 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, 1870cc featuring liquid-cooled cylinder heads for the CVO Limited and CVO Street Glide models.
Each Milwaukee-Eight engine produces up to 11 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 engine weighs the same as the engines it replaces, so all of its extra power contributes directly to improved acceleration performance and accelerates 11 percent quicker 0-100 km/h, equal to a two to three bike length improvement.
Efficiency gained in Milwaukee-Eight engine air flow and combustion, including the use of dual spark plugs per cylinder, delivers better fuel economy, depending on displacement and model, and a corresponding increase in range.
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, 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.
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.
The new 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.
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.
The front suspension features new Showa SDBV suspension technology that delivers the damping performance of a racing-style cartridge fork with linear damping characteristics and reduced weight.
Harley-Davidson Screamin’ Eagle Performance will offer a range of new ECE-certified products for Touring models, including Street Cannon Slip-On Mufflers and Heavy Breather Performance, Ventilator and High-Flow Air Cleaners. In addition, the new Screamin’ Eagle Milwaukee-Eight Stage I, II, III and IV kits enable riders in compliant countries to fully upgrade the performance of their bike to suit their riding style; from a passing power increase to a total engine upgrade delivering maximum performance (product compliance varies from market to market).
Harley-Davidson Custom Vehicle Operations (CVO) models combine prestige and performance in three limited-edition factory-custom motorcycles for 2017.
The 2017 CVO 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. Also new for 2017 are Contrast Chrome Slicer wheels and a seat reshaped for rider comfort. The CVO Limited also features a new custom paint scheme in four new colour combinations.
The 2017 CVO Street Glide motorcycle combines the power of the new Twin-Cooled Milwaukee-Eight 114 engine, the refined ride and handling performance of the new suspension, and a four-speaker, 600-watt Boom! Audio system that delivers state-of-the-art audio performance. Also new for 2017 are power locks for the saddlebags and fork controlled by a single security and locking key fob, and a re-styled seat cover. The CVO Street Glide is available in four new colour combinations for 2017.
The 2017 CVO Pro Street Breakout motorcycle combines high-intensity performance with a long, muscular look steeped in drag-racing attitude. Utilizing cutting-edge finishes and textures, the CVO Pro Street Breakout brings a darker look to the CVO line. The CVO Pro Street Breakout is powered by the Screamin’ Eagle Twin Cam 110B air-cooled V-Twin engine. Three finish choices include the new Starfire Black/Scorched Apple combination.
With the High Output Twin Cam 103 standard for all 2017 Softail models and the S Series cruisers with the Screamin’ Eagle Twin Cam 110 engine, Harley-Davidson continues to offer its most powerful cruisers ever.
