If you go on tour with your R1100S, with passenger or a motorcycle group, it is an advantage, when the driver can talk to other co-drivers over an interphone ✅ . Based on our experiences and those of our customers, we have opted for the Interphone system. There are two different possibilities of fixation of the interphone system at the helmet. A communication from bike to bike is given up to 200 meters line of sight. Also possible is the connect to the navigation or a bluetooth mobile phone. The latest version of this device is called the Interphone F4 and comes up with some new and improved features. The upgraded microphone against wind and noise, a stereo headset for better listening even at 180km / h and a communication up to 500 meters is possible with the Interphone F4. You need two pieces for driver & pillon rider or driver & driver. A brand new device at a great price is the navigation system X-Navigator, which is preinstalled with maps of 43 countries and equipped with a universal appropriate mounting for your motorcycle but also for scooters, quad bikes, ATV and bicycle. For your travel and tours, we can also recommend the navigation devices Garmin ZUMO 550, Garmin ZUMO 660 and the TomTom Rider II especially for motorcycles. For this GPS-devices you get the appropriate GPS-mount from us. Our mounting option for TomTom Rider II and Garmin ZUMO is a ballhead on which the RAM-mounting will be attached easily. The RAM-mounting must be fastened so, that the NAVI comes more to the center of the handlebars, otherwise the mirror will be covered too much. To hold your experiences on the tours visually, you need our BikeCam2. Our BikeCam2 is a waterproof camera combined with the Sony High Quality Solid State Recorder. With the BikeCam2 it is possible to make high professional recordings in a very exceptional way, by the helmet or the handlebar mount.
