Sena presents the SF4 communication kit, designed for motorcyclists with a passenger or for small groups.
For motorcyclists who wish to communicate with their passenger, the SF2 model with its Intercom communication system for 2 participants is the ideal solution. For motorcyclists riding in small groups, the SF4 model is equipped with an Intercom communication system for 4 participants operating within a range of 1.2 kilometres (0.8 miles). Both models allow motorcyclists to connect with their smartphones. Riders can listen to music and use the Intercom system simultaneously thanks to the Audio Overlay feature. Note: Audio Overlay works optimally on Android devices, but its features are limited on iOS devices.
