Biker-to-biker communication can now go up to a mile with the ground-breaking Scala Rider G4 PowerSet ($500). Each set comes with two factory-paired headsets that you can utilize with family, friends, and co-workers for easy, clear, long-reaching, and hands-free communication. The Scala Rider G4 PowerSet also features a unique 4-way intercom between two bikers and two passengers or 3-way intercom among three separate bikers. With the PowerSet, connecting with any other G4-enabled biker in-range is also made possible – it’s just like adding a friend on Facebook. Apart from these exciting conveniences, you can also connect the PowerSet with your mobile phone and mp3 player and also listen to FM radio.
