I am planning to put 17" straights on the wife's zs. We love the 18s but they are a bit hard for us with the baby in the back too.
They are marked and I will get the new pics I took on the weekend up soon. They are multi fit but I don't know what else they fit?! Would probably suit a zs with kit as they can just bump the arch when hitting a bump/jump.
Any ideas what they are worth? 2 tyres are under 3 months old and one was new on the weekend. One is wearing on the inside.
