Dual Outboard Rear Shocks Dual outboard shocks and the traditional rear fender make it unmistakably Sportster®, while next-generation performance takes the iconic name further than ever before.

INNOVATION Ride Modes, Rider Safety Enhancements, and a clear display to navigate them—all without compromising the Nightster’s timelessly handsome style. Four-Inch LCD Display The four-inch analog speedometer offers a classic, easy-to-read display, while the LCD screen below provides essential like Ride Modes.
