I can only comment about the Bridgestone S20 EVOS, but they make a HUGE difference for street riding. I didn't really think the stock tires were that bad until I made the change. In comparison, the stockers are crap.So I'm a casual rider, first bike, but I'm getting a hang of it.
Don't think I'll do track, just roads, and I'm starting to get a hang of riding, leaning more and more.
Should I switch stock tires ? Or is this discussion just for track ?
I'm too much of a newbie to know if tires are not that good.
The S20's are well worth the cost if that happens to fit your budget ($200 plus mounting/balancing cost). Sell the stock tires on eBay or CL to offset some of the cost......
