K1300GT with Z8s fitted twice now, very happy with them.
Z6s used previously on K1200 and K1300, no issues, performed well, solid in the wet and dry, and
easy to turn on the twisties, about 50% time 2 up.
Just back from 5000km Spanish Tour (2 up, full luggage), unfortunately a lot of wet days, tyres were solid all the way through, on both good surfaces and 'off-road' surfaces.
Back one is a a bit squared off now due to the long motorway runs back through the UK, still a few 1000 km left in them.
For both Z6 and Z8, I have, on a couple occasions, experienced high road noise (& strange vibrations, rumblings) from rear depending on the road surface, leading to me having to pull over and check tyres on the K1200, now it's just a quick TPM check on the K1300.
I'd recommend the Z8s, but tyres are very much a personal preference, everyone has their favorites.
