FOUR RIDER CONNECTIVITY & COMMUNICATION

The SF4 is the perfect device for riding with friends by providing connectivity for small groups, up to 4 riders.
 
The SF4’s 4-way intercom has a range over 1.2 kilometers (.80 miles) so you can easily stay connected with your group in open terrain.
 
The SF4 also uses smartphone connectivity, allowing for music streaming, taking and making phone calls, and hearing turn-by-turn GPS directions.
 
Most importantly, riders can listen to music and use the intercom simultaneously, using the Audio Overlay™ feature. Plus, with the Quick Charging capabilities, you will be ready to start your ride in no time.
 
Audio multitasking allows for seamless music fade-out for incoming calls or GPS directions, then fades right back to your tunes.
 

Music Sharing allows riders to share music and navigation instructions wirelessly via Bluetooth with companions or a passenger.
