Sorry, a bit late to this party (been away getting some rays..)
Mine came with the Pirellis, I managed to stick with them for 500 miles before ditching them for Tourance NEXT's. Pretty happy with the Metzella's at first then they wore quickly and squared a little, but that could have been the Scotland tour with wife and entire wardrobe! Now they have returned to the correct profile (A-hem....) and the are very very good in all weathers.
I had the Pirellis on the previous Tiger and we didn't gel there either - I just don't like the way they follow imperfections and banding on the road.
(so, I have two sets of rather under worn Scorpions in the garage - I could start a small shop
