Harley-Davidson, one of the most popular motorcycle brands, recently announced a new 107 ci and 114 ci engine known as the Milwaukee-Eight. In its first release of the 2017 motorcycle certification data, the U.S. The environmental protection agency (EPA) confirmed the “9th generation” two upgraded engines \u2013 a 107ci (1746cc), and a 114ci (1868cc) as well. However, the EPA listed only a few bikes for each brand-new engine.<\/p>\n\n\n\n

The motor takes its name from its birthplace and has twice as many valves as the “Twin Cam Engine,” which has been around since 1999. The New Harley-Davidson engine delivers more torque, faster throttle response, a smoother ride, better fuel economy, and improved fuel economy.<\/p>\n\n\n\n

Harley Milwaukee Eight 107 Vs. 114, which is more likely to last longer between these two engines? Throughout this discussion, I will compare both engines and answer the question of which one can be matched with a minor investment. I am also responsible for the question of what the performance difference is and which can be worth the<\/p>\n\n\n\n

A Brief Comparison Between Harley Milwaukee Eight 107 vs. 114<\/h2>\n\n\n\n

Harley claims the engines have a 10% increase in torque compared to previous models, but the factory didn’t release horsepower figures. Well, take a look at a short comparison below.<\/strong><\/p>\n\n\n\n

Harley Davidson Milwaukee-Eight Engine Include More Features<\/h2>\n\n\n\n

Harley has also confirmed that each head will have 4 valves, hence the name “Eight” (Milwaukee stands for the obvious):<\/p>\n\n\n\n

    \n
  • Improved cooling and a reduction in heat due to repositioned exhaust pipes.<\/li>\n\n\n\n
  • Idle speed is lowered from 1000 to 850 rpm.<\/li>\n\n\n\n
  • The engine profile is slimmer.<\/li>\n\n\n\n
  • Reduces clutch effort by 7% with help from the assist and slip clutch.<\/li>\n\n\n\n
  • At idle, a 75% reduction in vibration is provided by an internal counterbalancer.<\/li>\n\n\n\n
  • Improved drivetrain components, including a single camshaft, lighter valves, improved cover designs, and reduced powertrain noise.<\/li>\n\n\n\n
  • Designed to minimize engine air intake noise and maximize the air flow.<\/li>\n\n\n\n
  • Capable of providing 50 percent more electric power at idle for touring vehicles.<\/li>\n\n\n\n
  • The Harley-Davidson Big Twin engine has been improved and maintained the heritage of its predecessor.<\/li>\n\n\n\n
  • The cylinders have four valves each, a single chain is driven cam, dual plugs, counterbalanced, and rubber-mounted.<\/li>\n<\/ul>\n\n\n\n

    Complete Overview Of Harley Milwaukee Eight 107 vs. 114:<\/h2>\n\n\n\n

    Millions of miles and countless hours of testing have proven this system. Each part of the engine is updated and engineered to deliver more performance. Power and a classy look. A totally new experience awaits you on this ride.<\/p>\n\n\n\n

    Features<\/h3>\n\n\n\n

    There are 107 engines using precision oil-cooled cylinder heads, available in Street Glides, the Electra Glide Ultra Classic, Road Glides, and Freewheeler trikes as well.<\/p>\n\n\n\n

    Ultra Limited models, the Road Glide Ultra, and the Tri Glide will be offered in a Twin-Cooled version featuring liquid-cooled cylinder heads and radiators.<\/p>\n\n\n\n

    On the CVO Limited and Street Glide, you’ll find the twin cooled Milwaukee Eight 114 engine featuring liquid cooled radiators and cylinder heads.<\/p>\n\n\n\n

    Increase Performance<\/h3>\n\n\n\n

    With an increased displacement, the Milwaukee-Eight is a better alternative to the Twin Cam 103 or 110. A new motor will offer riders quicker acceleration off the line (about 8-11 percent faster at 0-60 mph) and during top gear (around 11-12 percent faster at 60-80 mph).<\/p>\n\n\n\n

    When stopped, the Milwaukee-Eight’s rubber-mounted counterbalancer cancels 75 percent of initial vibration, which makes stopping less of an eye-shaking experience.<\/p>\n\n\n\n

    Heat management can be improved by repositioning or relocating the exhaust pipe and relocated catalytic converter, as well as maintaining precision cooling of the cylinder heads.<\/p>\n\n\n\n

    Improved Acceleration<\/h3>\n\n\n\n

    All of Milwaukee-Eight’s extra power directly contributes to improved acceleration performance since it weighs the same as the engines it replaces. Compared to the Twin Cam High Output 103, the Milwaukee Eight 107 accelerates faster from 0-60 mph by 11 percent. Equivalent to about two to three bike lengths, and 11 percent faster from 60-80 mph in high gear, which is about one to two bike lengths.<\/p>\n\n\n\n

    However, 0-60 mph acceleration is 8 percent faster on the Milwaukee-Eight 114, 60-80 mph acceleration is 12 percent more quickly on the Twin Cam 110.<\/p>\n\n\n\n
