Hi Rasher - KTM quote a width of 1.01m for the plastic panniers and a total capacity of 70 litres so about 25 mm wider each side than my old Holan set up which I can live with.
Holan confirmed that they are only doing the new "INNOV PRO QR" pannier frames for the new bike and that my old panniers would not fit these. Helpfully suggested that I sell my old system and buy a complete new set of luggage from them
Not found the charcoal canister yet but no longer under the pillion seat where I have managed to squeeze in the KTM tool kit and a puncture repair kit
Other thing that will not fit off the old bike is the wind screen which has the bottom holes in different locations so something else to sell at some point having a Puig sports screen and a Givi touring screen. Just as well the screen on the new bike works well for me and so will not need replacing
