2025 Harley-Davidson® Nightster®

Features may include:

DESIGN

Cast wheels and LED lighting improve performance with style, and a fully blacked-out powertrain complements the bold vintage tank medallion and nostalgic Sportster® silhouette.

  • Blacked-Out Revolution® Max 975T Engine

All-black finishes adorn the high-revving, liquid-cooled Revolution Max 975T powertrain, which puts out 91 horsepower and 72 ft-lb. of torque.

  • Low Seat Height

27-inch seat height means easier step-over, a lower center of gravity for improved handling, and more confident flat-footed stops.

PERFORMANCE

Radical sport performance in classic cruiser form, the Nightster blends the benefits of high-revving, liquid-cooled power with iconic Sportster® design.

  • 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.

  • Air Box/Intake

A steel cover replaces the classic Sportster® peanut tank and hides a high-performance downdraft intake beneath.

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. The Nightster features three pre-set Ride Modes (Road, Rain, Sport) and two customizable modes, allowing you to fine-tune your settings for peak engine performance.
