I first purchased one of these for my S1000R, found I needed one on the XR even though I had the Carpuride fitted to the OEM mount. Phone would run out of battery with no power supply and would overheat if left on charge in a jacket or tank bag. The Evotech mount fitted to the lower part of the handle bar clamp bracket provides a clear view both the phone and the dash. It's also really easy to run power up from the battery! I did this with the Quad Lock USB Smart Adapter as did not want the messy use of the DIN.
Great product, highly recommend.
