just visually seeing those tires makes me ask way anyone would spend that much money, for such a sorry looking tire setup as those for use on a C14...
a sport bike maybe, but not a BigBerthaButt C14, carrying 2 people, in the rain...
nope. not this guy.... 
Why do you think those would favor a Sportbike vs. the Connie??
I don't see the logic.
visually.... the lack of sipeing and water venting pretty much every touring tire has...
I have ridden extreme amounts and miles in torrential rain, both 2 up and solo, and those simply do not show me "any semblance" of being a superior wet rainy road tire.
but;
I also read, and the description actually calls it SPORT...

it's just my opinion, we all have them, and for a tire that you cannot get "yet", it's all moot.
When they are available, and people buy them and run them, and tell us the mileage and confidence level on wet rainy roads, and how long that confidence lasts(miles) before swapping again, I just stick to tires with much deeper water grooves, and proven performance (that I have experienced). If I get 6k out of a pair of tires, that I paid < $350 for,(if I buy PR4's) I won't be switching soon. I'm still running PR3's, what can I say.
PR4's? $350

PR3's... @ $310...
I like them still...

even PR2's... if stored well... @ $270....

or a new never seen or ridden tire... for $525 (and why when there are 2 choices, for each exact same tire size, front and rear, they differ in price, but not differ in the spec sheet... whasssuuuuup wit dat'???)

ride safe.
