Thanks for that. This is quite a good review (with a few translation issues!).
I'm interested about the comments for some tires lacking neutrality and something about tilting. I've noticed that too. Just hired a GS1200 for a week and it had Anakees on it - I'd completely forgotten about the way they tip into a corner and don't really want to tip back out of it again. TKC 80s are the same.
I'm starting to wonder if this is the price yo pay for having chucnky tread.
