An update...
Ref my post above and compliments Scott the weaving I had at speed. I'm wondering if I've found the source of the problem. This morning as I protested to leave Switzerland, bike in the centre stand, front wheel off the ground. I discovered the steering bearings are all notch.
Bit surprised if I'm honest the bike had only done 25k miles. But that notchy/bumpy rotation was unmistakable.
So, would this cause the weave I experienced? I think it definitely explains the poor tackling at very low speed (sub 10mph). But at higher speed? Thoughts welcome.
Incidentally, discovered that even with a full tank I can get a similar feel coming on. I'm fully aware of it now, and in an on the road investigation - playing with the suspension settings - I've found that 2 helmets with sport damping irons it out a lot.
