Even the name Roadster implies, which is gladly used for the for the R850R, R1100R, R1150R and the R1150R Rockster, that Roadster and Rockster driver like to undertake long motorcycle trips. By preference, of course with a passenger or an entire motorcycle group. Especially in a group it is an advantage, if the biker can talk to the other bikers 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. For your travel and tours, we can also recommend the navigation devices from Garmin ZUMO and TomTom, especially for motorcycles. You have to look, when buying navigation devices, especially for the fact that they are suitable for motorcycles. Other products, like e.g. for cars, are not waterproof and do not fit on the offered motorcycle mountings. For the turbular handlebar of the R850R and R1150R we have for the navigation devices Garmin ZUMO and TomTom Rider II a handlebar mounting with Ram-ball with M10x1,25 thread in the program. The base of the GPS mounting is the ballhead on which the Ram-universal mount can be fixed easily. 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. 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.
