The SF4 is the ideal device for motorcycle outings with friends, providing a means of connection for small groups. The SF4's intercom allows communication between 4 participants and boasts a range of over 1.2 km. So you can easily stay connected with your group in open terrain. The SF4 also lets you use your smartphone to listen to music, take and receive calls, and listen to GPS navigation instructions. Most importantly, bikers can listen to music and use the Intercom system at the same time thanks to the Audio Overlay™ feature. What's more, the SF4 system recharges quickly: so you'll be ready to start your road trip in no time.
