I never know what is in mine:) but it always attracts a lot of attention on ride outs;) usually from ginger:P

No good for me i used to be able to complete these in under a minute…
As for top box, not the sort of thing i have considered for mine!
I have a Ventura bag does that count?
Yours is brilliant, think last ride out we had fresh chocolate cake!
Not quite on track, but the most interesting top box I ever saw was in France where a rider had a travel fridge bolted down to the carrier of a Transalp.
As the bike owner was French, and this was southern Brittany, I was kind of waiting for his mates to turn up with Hibachi’s, charcoal and another fridge with either the food or the wine.
Then he produced his beech kit from the fridge.
