I have been running Shinko tire for the last two sets of tires. I am NOT a performance geek (no offense intended) but they stick well enough for my needs, last a good while and are reasonably prices. All pluses in my book.
No offence taken.
I don't go as hard as i once did, and if I do decide to play the GSA or even the KLE is far, far better suited to "spirited" riding.
Everything I read about Shinko tyres pointed to them being a fairly good tyre, whilst not perhaps on the bleeding edge of grip. They are particularly well regarded in the Yamaha XS750 group and in fact the 100/90, 110/90 combination is marketed as a pair by the local distributor for XS750s and early Honda 75-0/4s.
If they do not prove t be as good as I hope, they were cheap enough that throwing them away will not be the end of the world.
