2026 Harley-Davidson® Nightster®

The Beginning of Something Better

At 481 lbs wet with a low 27” seat height, the 2026 Nightster carries its weight where it counts: low, centered, and in your control. Add a blacked-out 975T Revolution Max® motor, selectable ride modes, LED lighting, and legacy Sportster styling, and you’ve got an incomparably capable machine, no matter where you’re coming from.

Features may include:

Striking Style That Hits Your Mark

A new blacked-out powertrain with highlighted fins gives the 2026 Nightster a sharper, more aggressive edge, while its low 27” seat height, lightweight 481 lb. build, and vintage Sportster touches give it a profile that couldn’t be more Harley.

Hard-Hitting Blacked-Out Powertrain

Updated for 2026 with highlighted cooling fins, the blacked-out Revolution Max 975T powertrain on the Nightster hits harder on the dark, custom, sport-driven attitude riders have been asking for. You asked, and we listened.

Low, Locked-In Stance

A 27” seat height and classic rider triangle lock you into a balanced, confident riding position, whether you’re easing off the side stand or tipping it into the next corner.

Dual Outboard Rear Shocks

More travel than legacy Sportsters means a smoother ride so you can stay planted without losing the edge that makes the Nightster so much fun to ride.

Premium Brembo Brakes

All the stopping power you need. A four-piston Brembo caliper up front, single-piston in the rear, and floating rotors all around give the Nightster® the kind of stopping power that feels intuitive, balanced, and precise. Every piece falls into place to keep you in control of all 91 (HDI: 89) horses waiting under your right hand.

Full LED Lighting

Bright, low-draw LED lighting keeps you visible from every angle while throwing a clean, white beam to light your path after dark
