Sportster® S Model: Instrumentation
The Sportster® S model features a round 4.0-inch-diameter TFT screen (thin-film-transistor, a type of liquid-crystal display noted for high image quality and contrast) that displays all instrumentation and infotainment functions.
• All display functions are managed using buttons on the left- and right-hand control array, when the motorcycle is at rest or when it is in motion.
• The screen is covered with non-reflective glass to make it easier to view in most lighting conditions. Colours and the design of the display were selected to make the screen comfortable to view.
Sportster® S Model: Infotainment
The Sportster® S model display supports infotainment generated by the rider’s Bluetooth®-equipped mobile device. The motorcycle does not have an on-board infotainment system, and it is not equipped with speakers. Most infotainment functions also require a Bluetooth headset and speakers worn within a helmet (sold separately).
Sportster® S Model: Cornering Rider Safety Enhancements
The Sportster® S model is equipped with Cornering Rider Safety Enhancements by Harley-Davidson®, a collection of technologies designed to enhance rider confidence during unexpected situations or adverse road conditions. Cornering Rider Safety Enhancements are designed to match motorcycle performance to available traction during acceleration, deceleration, and braking, in a straight line or while in a turn. The systems are electronic and utilize the latest chassis control, electronic brake control and powertrain technology.
The Sportster® S model is equipped with a six-axis inertial measurement unit, or IMU, that measures and reports the lean angle as it navigates a turn. While cornering, available grip for braking or accelerating is reduced. Cornering enhanced technology takes this into account, and for optimal performance, intervenes differently when the motorcycle is leaned compared to when the motorcycle is upright.
Sportster® S Model: Ride Modes
The Sportster® S model offers selectable Ride Modes that electronically control the performance characteristics of the motorcycle, and the level of technology intervention. Three of the modes are pre-programmed, while two additional modes may be customized by the owner. Each Ride Mode consists of a specific combination of power delivery, engine braking, C-ABS and C-TCS settings.
The rider may use the MODE button on the right-hand controller to change the active ride mode while riding the motorcycle or when stopped, with some exceptions. A unique icon for each mode appears on the instrument display when that mode has been selected.
With the exception of the Road Mode, the rider may disable Ride Modes through the settings menu on the instrument display. The Custom Ride Modes need to be enabled by the rider through this settings menu before they can be selected with the MODE button during operation.
