I expect some to argue my point, so just take it for what it is worth... My opinion.
People seem to think that high performance tires are better than street tires. Street tires do not stick as well, however I have seen many people drag a knee on street tires at a track day. Traction is related tyo smooth. If you are scared a street tires is going to break from the surface at fast pace... and you concern is legit (i.e. worried about a wreck) the problem is not the tires, it is the rider.
Street tires pull away more rain than track tires or race tires, they last longer, and they are cheaper.
So where do they not seem to be better than a track tire?
Oh... they don't grip well when you are ham fisted and not smooth.
They do not cover up your mistakes when you ride sloppy.
They do not make you sound cool when you are talking to your friends.
Problem with a lot of riders is that that buy what they do not need. The tires make up for a lack of riding ability, but only soo far. A rider gets used to braking poorly and being very rough with the throttle and turn ins... then the rider want to ride his friends bike... He rides his normal crappy way and the bike goes down.... but it is not his fault. He blames the tires and his equally non-informed friends agree.
I will lean a tiger in farther than many people think is necessary on a bike that big. I have cut up with sport bike and kept up, sometimes passed them in tight sections. I did this on H rated dual sport tires. I garantee you that any normal street tire with out perform those.
I have had my RC out with my Race take offs on it... I got into some back road fun with a GSXr 1000 and his buddy followed from a distance. I killed him in every corner. Then after embarrassing him a bit, he pointed at my tires at a stop sign and said that was why... I traded him bikes... It took less than 2 minutes to prove him wrong.
So to get back to my original point... Buy what you want, but have faith that the "cheaper" street tire may in fact be the best choice for you riding.
