None of these are track-specific. They are considered performance street tires. I will continue to research the tires and add more information. I will also look into good sport tires that fit these bikes, but have longer life that may not be as good, so people don't need to frantically figure out what tires to buy.
Any possibility of getting this thread stickified for now? I may end up just creating one large thread with links to various threads about modifications (brakes, tires, track fairings, suspension..etc) as a 1-stop user guide area.. but for now, this'll do.
Yes, the larger the tire, technically the more input you'd have to give for it to lean. Wheels are designed for a specific width tire, so technically, wider isn't always better for a specific bike. Someone like Peanut who has experience racing and going hard on these smaller tires could probably chime in and tell you how the feel is, but with my bigger bikes, I've ridden both 180 and 190 tires and can't say I really felt a whole lot of difference. Because the 300 is so simple to throw around anyways as it is, I personally don't think you'd notice any negative effects, but don't quote me on that.
I will say, I am pretty sure I'll be getting the Battlax S20's in the 110/150 combo before Spring hits. It's one of Bridgestone's newest tires, a very good street tire but also good for track days. Their BT-003 has a more extreme tread pattern on it that wouldn't fair as well in wet conditions.
