Power distribution is managed efficiently to accommodate lighting, rider safety systems, and device charging. A USB-C charging port is integrated to support modern electronic devices during operation. This allows continuous use of navigation, communication, or audio equipment without relying on external power sources.
Instrumentation and Control Interface
The rider interface combines analog and digital elements. A 5-inch analog gauge serves as the primary visual reference for speed, preserving a traditional layout. A digital display within the gauge provides access to ride mode selection, safety system status, and system alerts. This configuration minimizes visual clutter while expanding functional capability.
Updated hand controls integrate ride mode selection, traction control interaction, and cruise control functionality. Control placement prioritizes accessibility without requiring the rider to remove hands from the handlebars. An adjustable brake lever allows fine-tuning of lever reach, improving braking consistency across different hand sizes and riding positions.
Ride Modes and Power Management Systems
The 2025 Harley-Davidson® Heritage Classic includes selectable ride modes that adjust throttle response and electronic intervention parameters.
