New Milwaukee-Eight Engine
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 carries the legacy of Harley-Davidson Big Twins into the future,” said Chief Powertrain Engineer Alex Bozmoski. “While respecting the essential Big Twin character, we’ve created an all-new motor. Every aspect of performance, durability and styling has been improved as a direct response to the voice of Harley-Davidson customers around the world.”
Retaining the classic 45-degree V-Twin cylinder angle, the Milwaukee-Eight engine produces up to 11 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 counterbalanced 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. Despite its increased power, the Milwaukee-Eight engine delivers better fuel economy compared to previous motorcycle models.
Milwaukee-Eight engines are offered in two displacements: the Milwaukee-Eight 107 (107 CID/1745cc) and Twin-Cooled™ Milwaukee-Eight 107 (107 CID/1745cc) for standard motorcycle models and the Twin-Cooled™ Milwaukee-Eight 114 (114 CID/1870cc) for Harley-Davidson® Custom Vehicle Operations (CVO)™ motorcycle models.
New Touring Suspension
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.
“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 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.
