Great tip and video. Have ordered two from amazon for my 2010 r1200rt. Hard to understand why other liner bags are so exhorbitant, particularly the BMW-branded. Much obliged!
A pannier /ˈpæniər/ is a basket, bag, box, or similar container, carried in pairs either slung over the back of a beast of burden, or attached to the sides of a bicycle or motorcycle. The term derives from a Middle English borrowing of the Old French panier, meaning 'bread basket'.
