Hi mate, can't help with the luggage options mate. When I traveled in UK aboard my 06 bike I simply used an Oxford tail pack bungee'd to the passenger pegs
Was simple to fit, a bit of webbing prevented any marks to the tail section, was cheap to buy the unit as always on offer/discount from M&P/MPS etc. And found it was fine for a weekend/short week. If you wish to carry more, get a rucksack and combine and take it steady
