With the introduction of the new Milwaukee-Eight V-twin for 2017, all of the bikes in Harley’s Touring family, like the Road King, make more power, run cooler, vibrate less at idle and get slightly better fuel economy. And all-new Showa suspension, with dual bending-valve technology up front that emulates a cartridge fork and hand-adjustable emulsion shocks in back with 15-percent more preload adjustability, does a much better job of soaking up bumps and maintaining control. The improvements have brought fresh attention to the H-D Touring family, which presented Harley with an opportunity to reinvigorate the Road King line with a custom version that should appeal to both current owners and converts.
