Engineers and designers scrutinized every bike-rider interface and, wherever possible, reduced the steps necessary to complete any given function to just one. New One-Touch levers now make opening the saddlebags and Tour-Pak trunk one-handed operations—a huge improvement over fussy systems of the past. The saddlebag lids now open outward using levers mounted at the front inside corner, so the contents can be accessed without leaving the saddle, and a new, auto-retractable trunk tether no longer flops out every time you close the lid. Engineers even fine-tuned the sound and the feel of the lid latches and hinges, so they open and close with the velvet-damped feel of worthy of a premium luxury car.
This One-Touch philosophy extends to Harley-Davidson's all-new Boom! Box infotainment system, which is by far the most impressive aspect of these new touring bikes. An unprecedented level of attention during the development stage was paid to studying rider interaction with the system: Telemetry measured how long it took to navigate menus; cameras recorded riders' eyes and fingers as they followed commands and manipulated controls, watching where they looked and for how long; haptics refined switch textures and keystrokes to provide better feel and feedback; and, wherever possible, voice-recognition technology was incorporated to make hand controls obsolete. Not only is Boom! Box stunningly complete, integrating audio, navigation, communications, and vehicle information in one seamless package, it's also the most intuitive and easy to use infotainment system we've ever encountered on a motorcycle, bar none.
