The Harley-Davidson Nightster is the next chapter in the Harley-Davidson Sportster legacy – a leap forward in performance and design built on a foundation laid 65 years ago. An instrument of expression, the Nightster features the all-new  Revolution Max 975T liquid-cooled V-Twin engine tuned for tremendous torque at low RPM, delivering strong acceleration from the start with robust power through the mid-range. We’ve put the sport back into our Sportster models.
