I have the non tour model. Does anyone have or know about a bag that would fit on the passenger seat without having to have a backrest ?

Wolfman makes some excellent tailbags that are easy to secure. https://wolfmanluggage.com/collections/tail-bags/products/overland-duffel Also, CycleGear has some waterproof duffles - think they come in 3 sizes as well.
