For 2017, Harley-Davidson is launchingthe 9th generation the its venerable large Twin, called the Milwaukee-Eight. That is named in respect of that birthplace and also its variety of valves—twice as plenty of as found on the Twin cam motor that’s been in the lineup because 1999. Harley-Davidson states the brand-new engine platform provides much faster throttle response, more torque, better sound, boosted fuel economy and a smoother ride.

Other transforms for 2017 include all-new front and rear suspension for Touring models, obtainable ABS and Smart Security device for the Street 500/750 models, update CVO models (Limited, Street Glide and also Pro Street Breakout) and also a full choice of street-legal Screamin’ Eagle Performance contents for the Milwaukee-Eight, including Stage I, II and also III kits that supply up come 24 percent much more torque.

Cutaway the the Milwaukee-Eight 107, which Harley-Davidson states offers much faster throttle response, much more torque, far better sound, boosted fuel economy and also a smoother ride than the Twin camer 103.


The Milwaukee-Eight, which retains the classic 45-degree V-twin architecture, will certainly power all 2017 Touring and Trike models, in two displacements and also three variations:

Milwaukee-Eight 107 (107 cubic inches, 1,750cc) with precision oil-cooled cylinder heads for the Street Glide, Street Glide Special, roadway Glide, road Glide Special, electrical Glide Ultra Classic, road King and also Freewheeler modelsTwin-Cooled Milwaukee-Eight 107 through liquid-cooled cylinder heads because that the Ultra Limited, Ultra minimal Low, roadway Glide Ultra and Tri Glide Ultra modelsTwin-Cooled Milwaukee-Eight 114 (114 cubic inches, 1,870cc) with liquid-cooled cylinder heads because that the CVO minimal and CVO Street Glide models

Compared come the Twin cam 103 and 110, the Milwaukee-Eight’s boosted displacement, greater compression ratio and four-valve cylinder heads, which provide 50 percent more intake and exhaust flow capacity, result in 10 percent much more torque throughout the board. Bikes equipped v the brand-new engine are declared to accelerate much quicker off the heat (8-11 percent faster at 0-60 mph) and also in top equipment roll-ons (11-12 percent quicker at 60-80 mph).


Better air flow and combustion, including the usage of double spark plugs because that each cylinder, are said to boost fuel economy. Precision oil or fluid cooling of the cylinder heads as well as repositioning the rear exhaust pipe and relocating the catalytic converter improves heat management, giving a much more enjoyable riding experience for the rider and passenger.

As with the Twin video camer engine, the Milwaukee-Eight’s rocker arm-actuated valves never need adjustment as they space a hydraulic video camer tensioner. Yet instead the the pair Cam’s double camshafts there’s a single, chain-driven camshaft that’s lighter, quieter, less complicated and reduces friction. The rubber-mounted Milwaukee-Eight provides an interior counterbalancer come cancel 75 percent of major vibration in ~ idle, because that a much less eyeball-shaking suffer at stops.

For 2017, the Milwaukee-Eight 107 (107 cubic inches, 1,750cc) with precision oil cooling will certainly power the the Street Glide, Street Glide one-of-a-kind (shown above), roadway Glide, roadway Glide Special, electric Glide Ultra Classic, roadway King and Freewheeler models.


Harley states the brand-new engine’s diminished mechanical noise permits the exhaust note to take on richer tone. Various other improvements include a 50 percent rise in charging calculation for powering accessories, slimmer primary and also air cleaner consists for much more legroom, and—always important on Motor company machines—enhanced curb appeal. And all bikes with the Milwaukee-Eight room equipped with a low-effort Assist and Slip Clutch.

Their above look, distinctive sound and also massive torque make them soon recognizable, but the Milwaukee-Eight® 107 and Milwaukee-Eight® 114 engines take it the Harley-Davidson® V-Twin to a location it’s never ever been. They’re the most powerful, coolest-running motors we’ve ever before built. Smoother, more powerful and an ext durable. With crisper throttle solution and truer, cleaner sound. 4 valves every cylinder, single chain-driven cam, dual spark plugs, counter-balanced and also rubber mounted. Developed and also proven over plenty of miles and millions that hours. Every single part is new, engineered to provide you more performance and much more of the emotion you desire from an engine. Today, it’s a whole new ride.
