We use the wording "Custom" because the website allows you to configure the communication system you would like to have installed. There are choices for plug in type headsets and options for wireless bluetooth headsets.
If you are interested in one of the J&M plug in style headsets, you have the option of going Universal or Integrated.
Universal headset can be installed by using the manufactures instructions. What we do as part of the custom install is make sure the speakers are recessed back into the poly-styrene (when applicable).
The integrated style headsets need to installed by authorized J&M dealers. There is not a clamp like you would find on a Universal Headset. A small port is made on the left side of the helmet for the upper cord can plug into. Again, as part of the custom install, we make sure the speakers are recessed back into the poly-styrene (when applicable).
We install these headsets as they are ordered. I am not sure if I have any images of the Shoei RJ Platinum R with the J&M installation. I will send a couple of photos to try and show the difference between Universal and Integrated.
