Key Features of the 2025 Harley-Davidson® Low Rider® ST

Milwaukee-Eight® 117 H.O. Engine

At the heart of the 2025 Low Rider® ST is the new Milwaukee-Eight® 117 H.O., tuned for stronger mid- and top-end thrust so you can stay on the gas longer. Redline increases from 5,600 rpm to 5,900 rpm, expanding the engine’s usable range and giving you a broader window to execute decisive passes or hold a gear through sweeping back roads. The Heavy Breather intake faces forward to maximize flow and intake tuning length, contributing to improved charging efficiency and peak torque. Together with the refined two-into-one exhaust, the engine breathes freely, responds immediately, and maintains the signature V-Twin pulse that defines Harley-Davidson® performance.

Frame-Mounted Fairing Shaped by CFD

Inspired by classic FXRT profiles, the Low Rider® ST fairing is more than a nod to history. It is a lightweight, frame-mounted design engineered using computational fluid dynamics to refine airflow around the cockpit. The result is more stability at speed, less head buffeting, and a calmer pocket of air around the rider. A color-matched finish and a reshaped headlamp area modernize the look, while the frame mounting prevents the bars from carrying the fairing’s mass, keeping steering feel light and precise during quick transitions or low-speed maneuvers.

Tall Monoshock Rear Suspension

The raised rear ride height and tall monoshock deliver two key benefits: added cornering clearance and a more controlled chassis under load. You will feel the difference when you link S-curves or encounter uneven pavement—composure remains intact, and the bike resists wallowing. This setup supports spirited riding without sacrificing comfort on longer days. It also contributes to the Low Rider® ST’s unmistakable stance, lifting the tail to accentuate the fairing-forward silhouette while keeping the wheelbase and geometry in a sweet spot for stable, confidence-inspiring handling.

Two-Into-One Exhaust With Saddlebag Symmetry

The updated two-into-one exhaust does more than sharpen throttle response; it cleans up the bike’s profile and rebalances the rear end. By creating saddlebag symmetry, it enables practical, balanced storage while maintaining ample lean angle. The exhaust’s refined routing and finish integrate seamlessly with the bodywork, highlighting the ST’s purposeful design language. It also serves as a strong foundation for customization, whether you plan to fine-tune acoustics or prioritize maximum flow with future upgrades that complement the Milwaukee-Eight® 117 H.O.

Four-Inch Display, Ride Modes, and Rider Safety Enhancements

Information and control are centered around a four-inch instrument display that pairs an analog speedometer with a multi-function digital screen. You can access available Ride Modes, view the gear position indicator, monitor tire pressures via TPMS, and check trip data without visual clutter. The available suite of Rider Safety Enhancements supports you in changing conditions, while USB-C charging keeps your devices powered for navigation and communication through your Bluetooth® headset. Updated hand controls make on-the-fly adjustments intuitive, including a repositioned flash-to-pass and an adjustable front brake lever to dial in feel.
