Pilot Power Pure SC tires are waaay on the sporty side of things and I'd be
VERY surprised if they had better then just average grip in the wet, since that's
not what their intended use is.
It's the type of tire Gilera Runner 200, Derbi GP1 250 and similar scoot owners
would use, for maximum lean angles and pushing it hard everywhere.
What I CAN recommend that works great in the rain is Michelin's City Grip which
I have on my Agility 125. Not that tire does NOT care if it's raining or not, it's
simply amazing in the wet.
Might not offer ultimate sporty riding grip on the dry, but it should last a long
time and is, again, amazing in the wet and/or bad slick city roads.
That's what going on my Downtown as soon as possible.
Hope they're available for your scoot though, but they should be.
They also like heavier scoots then my A125 from my experience, and should
work great on yours.
