Just noticed in my handbook for the MK3 that all up weight (excluding bike) is 220kgs so we weren't that much over the top. Given it a good clean today and have to say I was mighty impressed.
It did everything asked of it and for a relatively small capacity machine, what more do you really want, I think we could have done a longer tour no problems, just needed to leave out some of the unnecessary's we took.
Thing I might try is substituting the top box for a bag next time. Similar capacity but the position of the box restricts rider and passenger movement, ok if you've a 45kg pillion, not so good if he's 90kgs!. . unless I can rig a way off moving the box back 3-4 inches.
