Hell0 everybody.
I am a new member from Italy
I have GS500 E 2003. It is my first motorbike, I am very happy of my little Baby.
Now I organizing a Europe trip whit my little Baby. 3 week of road, without destination.
Those are known here as Panniers - or side Panniers. Those in particlar are Givi keyless ones - Givi E41 Keyless 41 litre Monokey Motorcycle Panniers - and quite expensive.
I was lucky enough to have a set included on my bike when I bought it. Thay might be a bit big for the GS500.
