MILWAUKEE – Harley-Davidson this morning unveiled a new engine, the ninth Big Twin in its history, dubbed the Milwaukee-Eight. It will be offered in two displacements: the Milwaukee-Eight 107 (107 cubic inches/1,750cc) and the Milwaukee-Eight 114 (114 cubic inches/1,870cc).
The company says the new engine “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 engines retain a 45-degree V-Twin cylinder angle and 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.”
Additionally, Harley-Davidson said it’s offering new front and rear suspension on its 2017 Touring models.
“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.”
The suspension upgrade will enhance comfort, control and performance. 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 Milwaukee Eight 107 engine will be used in standard motorcycle models, while the Milwaukee-Eight 114 engine will be used in the CVO Limited and CVO Street Glide models.
