GIVI 357 rack you will lose the ability for your passenger to use the grab rail due to width of both Corbin & Sargent seat. After her 1st ride on the FJR, she looked at my VFR 1200 "you're so much comfortable." I'm going to put the stock seat on the back along with GIVI topbox and will ask her again. She rides maybe 2 times a year, so I don't know when she'll ride again.
