I want to install the largest hardbags possible on my 2004 VTX1300s. From my online hunt the best I have found for the price are the Tsukayu Strong large hardbags, holding 40 liters each! The only provision I am concerned about is that, from my understanding, you have to have the tail lights changed to mounted LED tail lights on the hardbags. Also, will those bags interfere with the passenger floorboards? Anyone have any advice?
