The S11 seems hard to get these days, at least over here. They were already fitted to my 1100 when I bought it and I found them good, even though I wasn't sure if they were reccomended for the Wing. I still think the 880 is the better tyre.
I put an S11 on the rear ofmy 81 standard this spring. I think it's great. It is a wider tire than what I replaced too, for the same nominal size. It replaced a Dunlop.
I now have a fully loaded 93 Aspy that I am watching for tire comments here on. The tires will need replacing at the latest next winter- in the mean time their noise is making me crazy particulary when turning. Sounds like a truck! Any GL1500 recomendations would be welcomed.
i run spit fires on my wing and you can still get them from j and p cycles its not listed online you have to get the free catalog but they are in there you just have to dig for them they sell the front tire with raised black or white lettering or just plain un raised letters, the rear tire is just un raised lettering they run great in wet or dry, no traction problems yet
