The 2025 Harley-Davidson® Street Glide® is a touring motorcycle configured around measurable outputs and integrated systems that support extended travel. It uses a liquid-cooled Milwaukee-Eight® 117 V-Twin that produces 130 ft-lb of torque and 105 horsepower, with an estimated fuel economy of 44 mpg and a laden seat height of 26.4 inches. The platform adds hand-adjustable rear shocks for quick preload changes, a 12.3-inch color TFT touchscreen for navigation and settings, and a suite of rider-assist features for braking and traction. Aerodynamic development centers on the Batwing fairing with integrated LED lighting, and the chassis rolls on contrast-cut wheels sized 19 inches in front and 18 inches in back.
Powertrain Output and Thermal Control
The Milwaukee-Eight® 117 V-Twin is configured for accessible torque with consistent temperature management during slow traffic and highway use. Liquid-cooled cylinder heads and a discrete center-mounted radiator manage heat while preserving the motorcycle’s silhouette. This arrangement supports the rated 130 ft-lb torque figure along with 105 horsepower, which helps with passing maneuvers and steady cruising.
Breathing Efficiency and Intake Design
A high-performance touring intake increases internal volume to improve airflow to the cylinders. The intent is to support airflow at typical touring engine speeds, helping the engine respond predictably while maintaining stable temperatures alongside the liquid-cooling system.
Suspension Adjustment for Variable Loads
The 2025 Harley-Davidson® Street Glide® uses quickly adjustable rear suspension to accommodate riders who change payloads between solo commuting and two-up touring with luggage. Hand-adjustable preload lets the rider maintain geometry and ride height as loading changes, which supports consistent steering and braking feel across different conditions.
Aerodynamic Batwing Fairing and Integrated Lighting
Aerodynamics were developed using computational fluid dynamics to shape the Batwing fairing for rider comfort and smooth flow around the cockpit. The LED signature lighting is integrated into the bodywork, which creates a clean surface and reduces protrusions that can disturb airflow.
Wheel Sizes and Contact Patch Management
The wheel specification places a 19-inch wheel at the front and an 18-inch wheel at the rear. Contrast-cut finishes provide visual definition without affecting the stated performance intent. Tire selection is matched to the wheel sizes and touring geometry for predictable feedback during lane changes and extended sweepers.
Cockpit Layout and Seating Dimensions
The cockpit groups key information on a 12.3-inch color TFT touchscreen that centralizes navigation, media, ride modes, and alerts. Seating uses a one-piece design shaped for sustained comfort on multi-hour rides. The laden seat height of 26.4 inches gives many riders a secure reach to the ground, which can help at low speeds and during parking maneuvers.
Infotainment Interface and System Control
The 12.3-inch TFT functions as the main interface for navigation and infotainment. Consolidating navigation and vehicle settings on one screen reduces cluster complexity and supports quick checks at fuel stops. The interface also presents prompts and alerts from rider-assist systems and the tire pressure monitor for a single point of reference.
Selectable Ride Modes and Custom Tuning
Three pre-programmed ride modes allow the rider to adjust throttle response and intervention thresholds with a single button press. The modes are Road, Sport, and Rain. A user-defined option lets riders set a custom map to match personal preference for response and control. Mode selection is indicated on the central display so configuration can be verified at a glance before setting off.
Audio System Architecture and Output Rating
The fairing houses speakers that project toward the rider, powered by a four-channel amplifier. The total output rating is 200 watts, which equals 50 watts per channel. The arrangement focuses on spoken navigation prompts and music clarity at cruising speed. Positioning the speakers within the fairing reduces the chance of blocked output by luggage or apparel and keeps wiring within the fairing structure for service access.
Core Safety Functions for Braking and Traction
The 2025 Harley-Davidson® Street Glide® includes several rider-assist systems that address traction during acceleration and deceleration as well as braking. A standard Anti-lock Brake System is designed to help prevent wheel lock during straight-line emergency stops and can improve control for a wide range of riders. Electronic Linked Braking applies pressure to both wheels when the rider uses the front lever and may adjust linking at lower speeds or for lighter requests. A Traction Control System reduces excessive rear-wheel spin during straight-line acceleration, which is valuable when road surfaces are slick. Drag-Torque Slip Control helps limit rear-wheel slip during abrupt downshifts or when the rider reduces the throttle quickly on low-grip surfaces, which can stabilize the chassis as gears change. Vehicle Hold Control keeps the motorcycle stationary on grades until the rider deliberately moves off, which can simplify restarts on steep ramps. A Tire Pressure Monitoring System alerts the rider on the information display when pressures are outside the recommended range.
Cornering-Aware Control Strategies
Cornering Rider Safety Enhancements add lean-sensitive behavior to braking and traction features. Cornering Enhanced ABS considers lean angle because the pressure needed to limit slip while cornering is often lower than the pressure used when upright. Cornering Enhanced Electronic Linked Braking can alter the front and rear proportioning during braking while leaned, which helps the motorcycle track the intended path through a curve. Cornering Enhanced Traction Control manages rear-wheel slip during corner exit as the motorcycle transitions from lean to upright. Cornering Drag-Torque Slip Control refines the downshift stabilization logic by referencing lean angle, which can reduce disturbances when changing gears mid-corner.
Fuel Economy and Planning Considerations
An estimated fuel economy of 44 mpg is provided for the 2025 Harley-Davidson® Street Glide®. The number is an estimate and will vary by loading, environment, and pace, yet it provides a clear baseline for trip preparation.
Trim Selections and Paint Programs
Two trim tracks are available. Chrome trim offers Billiard Gray, Vivid Black, Atlas Silver Metallic, Blue Burst, Brilliant Red, Iron Horse Metallic, and Mystic Shift. Black trim offers Billiard Gray, Vivid Black, White Onyx Pearl, Brilliant Red, Iron Horse Metallic, Purple Abyss Denim, Whiskey Firestorm, Midnight Firestorm, and Mystic Shift. Factory Custom selections are part of the program, with Whiskey Firestorm and Midnight Firestorm using flame layouts and Mystic Shift presenting a color shift from gunmetal to purple to blue and toward orange under strong light.
Dimensions and Ergonomic Notes
The laden seat height of 26.4 inches provides a modest reach to the ground for many riders, which can aid balance during stops and low-speed turns. The one-piece seat profile complements the fairing’s protection by keeping the rider positioned in a calmer air pocket that results from the aerodynamic shaping. The interaction between seat height, fairing development, and wheel sizing aims to present a predictable ride across highway and city segments.
Schedule a Test Ride Today
If you want to confirm how these systems operate in daily riding, schedule a test ride and evaluate the Milwaukee-Eight® 117 torque, the cooling performance, and the response from the ride modes on familiar roads. Our team will set a preload for your expected load and review the functions of ABS, linked braking, and traction control so you can experience the interventions during controlled stops and starts. We will also demonstrate the 12.3-inch TFT interface for navigation and show how the audio system integrates with prompts and music at cruising speed. A short route will let you sample cornering-aware braking and traction features as you build speed through a series of curves. Contact Speedway Harley-Davidson® near Winston-Salem, NC, to book a time that fits your schedule, and we will have a 2025 Harley-Davidson® Street Glide® prepared for your ride.
