BIG NEW HD MOTOR…The all new, big displacement motor from Harley-Davidson is impressive I tell yas. Here’s my early take on the Milwaukee Eight as it launches into the market.
The Milwaukee-Eight engines will power the 2017 model year Touring and Trike motorcycles.
The motor’s styling is sleek, modern and continues to show off that classic Harley-Davidson V-Twin power look that many of us have grown to appreciate and even love over the years.
Every part of these motors is new. Yes, a clean-sheet design from the talented engineers and designers at the Motor Company. According to Harley-Davidson, they are the most powerful, coolest-running motors they have ever built and come with crisper throttle response and a truer, cleaner rumble-sound.
Massive rocker covers, big cylinder fins.
As you can see in the photo on the right, the rocker covers and cylinder air fins are massive. With 4-valves per cylinder, there’s a lot of action going on under those engine tops but word is that engine noise is reduced compared to the Twin Cam.
The new Milwaukee-Eight motor is apparently quieter, yet still provides a rich, quasi-loud exhaust tone. There’s no mistaking the traditional Harley-rumble from this powerplant according to media reports.
The all new Milwaukee-Eight 107 and Milwaukee-Eight 114 engines are all Harley-Davidson.
These Milwaukee-Eight V-twin motors are about power.
According to Harley-Davidson’s press release, each new Milwaukee-Eight engine produces 10% more torque than the Twin Cam engine it replaced.
The Milwaukee-Eight has quicker acceleration.
The Motor Company spec information indicates that the 107ci accelerates 11% quicker 0-60 mph and 11% quicker from 60-80 mph in top gear…significant improvement compared to the Twin Cam 103ci.
The 114ci motor accelerates 8% quicker 0-60 mph and 12% quicker 60-80 mph…significantly faster than the Twin Cam 110ci it replaces.
The Milwaukee-Eight has Reduced Vibration
These new engines are rubber mounted so some vibration will be always be noticeable but, the engineers at Harley-Davidson use an internal counter balancer that now cancels 75% of primary vibration at idle. The feel, while still classic Harley-Davidson, is more refined and more comfortable.
The Milwaukee-Eight motor is offered in two displacements and three variations:
107ci Displacement – Oil-Cooled – (1750cc, 92.5hp) 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.
107ci Displacement – Liquid-Cooled – (1750cc, 92.5hp) featuring liquid-cooled cylinder heads for the Ultra Limited/Ultra Limited Low, Road Glide® Ultra and Tri Glide® Ultra models. The liquid-cooled engines are branded by Harley-Davidson as “Twin-Cooled”.
114ci Displacement – Liquid-Cooled – (1870cc, 100.6hp) featuring liquid-cooled cylinder heads for the CVO™ Limited and CVO™ Street Glide® models. Also branded as a “Twin-Cooled” Milwaukee-Eight.
My Bottom Line…
From all I’ve seen and read since the unveiling on August 23, 2016, the power characteristics of the classic Harley-Davidson engine culture remain…strong low-end torque, broad and flat curve through the mid-range that is ideal for the Touring rider.
