Welcome to the forum, nice machines, not a big fan of the side covers of the new XJR, but a great reliable engine which is around a long time.
Are you heading to the UGP?
Touring tips. Best sat Nav is a good map no batteries required
and stopping to ask people for directions in europe can be a very enjoyable experience.
A good smartphone works well if you do not want the expense of a full blown Sat Nav, but if you do it is hard to beat Garmin.
Luggage is a personal thing and I personally prefer hard luggage and a good tank bag, do not over load the top box as it can cause handling issues.
Balance a full top box with a full well attached tank bag
