Yeah I have heard the K60 is a bit interesting on wet road. As the tyre changes depending on size the 130/80-17 doesnt have the continous line down middle so unsure what difference that makes.
It’s mostly around longevity. The bigger heavier bikes chew tyres out, so the centre ridge helps reduce that. Block movement generates heat, heat speeds up tyre wear. The E07 in my size also has a centre ridge but it’s stepped, so as the tyre wears the centre ridge first becomes continuous, then grows wider.
Ridge won’t affect grip for the most part on sealed roads (cornering), but obviously both tyres will have a weak spot for mud/clay or anything else where the ridge stops the tyre from biting down.
