Harley-Davidson’s Custom Vehicle Operations division is at it again with a revised CVO Street Glide model for 2019. The newest “SG” sports a new Boom! Box infotainment system with some serious speaker packages, and it comes with a choice of three distinct finish categories; bright, dark and really dark. Power comes from the Milwaukee-Eight 117 that makes its sophomore appearance and brings its “guns” to the table with oodles of torque and a new color band as a model-year identifier. There’s plenty more to see, so let’s get into the details of Harley’s top-shelf custom-tour bike.
