Metzeler Z8s ???

Hey All,

Checking to see if anyone is running the newer Metzeler Z8s on their GT?
The Z6s came stock on my '10 and after 7400 miles they are getting a little on the thin side.

The Metzeler site lists the Z6s for the K1300GT (F- 120/70, R - 180/55) and for the new K1600 it's the Z8s (F-120/70, R - 190/55). Both the Z6s and the Z8s are "ZR" rated.
Also, the the Z8s come in the 180/55 size.

Metzeler Z8's

Just installed a set on 05/12 in conjuntion with my 36K major service, due to other obligations I have only had a chance to put 50 scrub in miles so far.

I have run Z6's for the first two changes and switched to Michelin PR2's ever since, I am not totally sold on dual compound tires, they seem to develop strange wear patterns during the last 1/3 of their life. My intial impression of the Z8's is they ride a bit "softer" than the PR2's, turn in is similar due to to both tires having a rounded profile. I'm a flow rider and prefer smooth consistent cornering rather than snap transistions.

75% of my riding is fully loaded and 2 up, mileage on the Michelin has been 6500-7000, will be happy to duplicate this mileage. I will be interested to follow this thread and will update my impressions as I pile on the miles.

PS Hwy 36 from Red Bluff to Fortuna is spectacular right now!

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.
