Three preset ride modes, Road, Sport, and Rain, allow the motorcycle to adjust power delivery and engine response to match surface and weather conditions. A customizable mode can be configured to specific rider preferences for throttle mapping and engine braking behavior.
The integrated audio system features fairing-mounted speakers powered by a 200-watt, four-channel amplifier. Each channel delivers 50 watts, ensuring balanced audio clarity across low, mid, and high frequencies. The system is designed to maintain audio quality even at highway speeds while maintaining the aerodynamic integrity of the fairing.
Advanced Safety and Control Systems
The 2025 Harley-Davidson® Street Glide® includes the Rider Safety Enhancements from Harley-Davidson®, a suite of technologies that assist in maintaining traction, braking control, and stability. These systems operate continuously to help preserve balance under varying conditions of acceleration, braking, or lean angle.
The Anti-Lock Brake System (ABS) prevents wheel lock during straight-line braking, allowing the rider to maintain steering control in emergency stops. The Electronic Linked Braking (ELB) system automatically distributes braking force between front and rear wheels to achieve effective deceleration with reduced effort. ELB dynamically adjusts the ratio of braking force depending on speed and pressure applied, disengaging at lower speeds for smoother control.
The Traction Control System (TCS) reduces rear-wheel spin during acceleration, especially on wet or uneven road surfaces. The Drag-Torque Slip Control System (DSCS) mitigates excessive rear-wheel slip during abrupt downshifts or throttle roll-off by managing powertrain torque, preventing rear-wheel lock.
For additional stability during starts on inclines, Vehicle Hold Control (VHC) temporarily holds brake pressure after the lever or pedal is released. This feature prevents rollback on slopes until throttle is applied. The Tire Pressure Monitoring System (TPMS) continuously monitors air pressure and alerts the rider when it falls outside of optimal levels, helping preserve tire life and consistent performance.
The 2025 Harley-Davidson® Street Glide® also includes advanced cornering systems that adjust based on lean angle. The Cornering Enhanced ABS (C-ABS) adapts brake pressure when the motorcycle is turning, optimizing traction and stability. Cornering Enhanced Electronic Linked Braking (C-ELB) modifies braking proportion between front and rear wheels during lean to maintain the intended path. Cornering Enhanced Traction Control (C-TCS) adjusts power output to limit wheel slip through corners. Cornering Drag-Torque Slip Control (C-DSCS) stabilizes rear-wheel behavior during deceleration on wet or low-traction surfaces.
Each of these features functions independently and in coordination to ensure predictable handling, maintaining control without interfering with rider input.
