Put these on My K1200 last summer, some ride reports I made on another forum.
250 miles on the Shinko rear /Pilot Activ front last night and all is good, Thought it was a bit wandery in the front at first but there was wind, on the ride home it was tracking like on rails including some "just wet" roads. tar strips were a non issue, No rain grooves to test "following" yet.
Over 3K on the combo now, just got back to Wisconsin, went to south Georgia, the Barber vintage festival, and back. I am quite pleased with both front and rear. 2 days of damp to wet including an hour or so of twisties in the rain with no issues at all till the connie rider I was with bailed out, and we changed to a less twisty state road in western Tennessee. Last two days were on the slab at 75 with strong gusty side winds, no problem.
