I have used several Yoko Avid Envigor tires. IMO it is a great RF tire, but not so great as a tire for the twisties. I have worn out a couple of P1 tires, but even with 36+ PSI in it, does not seem to want to turn easily. I think it is easier to turn than a Yoko, but not as easy as a Snowcontrol. I am very happy with my Snowcontrol, but I can't find a replacement. I have a partially worn out SnowControl, but am not excited about having a tire with significant use remounted.Terry, I'm running a driveguard on my 18 right now. And there's a new one in my garage right now on hold for another bike but if you come here I'll be happy to sell to you and install. Personally, I'll be going back to either a Yokohama avid envignor or try a P1.
I don't have personal experience, the word from others is the P7 is a slip-n-slide tire, unlike the P1 which has great reviews. I have probably 100k miles on yokos. Almost got the P1 last time, got the driveguard. Don't like it as much as the yoko.Been looking for a P-7 Pirelli 195-55 R16, also being discontinued, really liked that tire, and might consider the Yoko, somewhat like twisties, not so aggressive as on a rocket, but within the F6B limits of physical restraints.
Would like inputs, $170 the avg selling price.
