What do you lot be taking with you?
This is exactly what my bike looked before I unloaded when I arrived home after spending 2 weeks in Southern France with my wife as pillion. The top box had rain gear, wine and pressies for the family.
Camera was in the tank bag with toiletries and other bits required in a hurry, all the rest was in the panniers.
Mine usual packing is 4 pairs of socks 4 pairs of jocks and 3 of everything else I require (except the wife). Moto is travel light and wash one wear the other
and one spare
This is from years of mountaineering and having to carry stuff on you back. The only extra I have ever strapped to the bike is a tent.
Once rode a friends FJR1300 with my wife pillion back from Malaga, with no top box and no panniers. We flew down from Cork with all our gear and just 2 extendable tank bags and took a week to return to Roscoff
