The SENA SF1 Communication System, designed by Sena, is specifically crafted for rider-to-passenger communication. It offers 2-way intercom communication with a range of up to 100 meters in open terrain. The SF1 can be connected to a smartphone or GPS device for listening to music, making or answering calls, and receiving navigation prompts. Additionally, it features Audio-Overlay™, quick charge battery, and microphone mute. When paired with the Sena SF Utility App, device settings can be configured, and the quick guide can be viewed. The talk time is up to 13 hours, a full charge takes approximately 1.5 hours, and a quick charge of about 30 minutes provides up to 4 hours of intercom use.
