Well a few weeks back I upgraded from my 04 zx10r to an 07 10r, and couldn't be happier.Coming off Metzler M1's on the old 10, to supercorsas on the new, the supercorsas seem to have a lot more grip.. in the dry! However in the wet they have nothing!
Went for a ride yesterday afternoon (nice sunny day) to the GF's house, about 40kms away, and that was all fine and dandy, however this morning I had to go to work, and it had been bucketing down over night. I havent really had the Supercorsas in the wet yet, and have been very hesitant to do so, however i decided to give them a go this morning, just being very delicate... Got out onto the hwy with out any dramas, however at 90-100kmh in a straight line i was getting the back end constantly step out! It was ridiculous! It felt like riding on ice and I was being as delicate as possible.
I ended up deciding it wasn't worth the risk, there is a little bit of a semi-twisty section on the way, and that would have been a bundle of laughs, ended up turning around about 3km out of town and riding back and getting the misses car..
So I guess this is just a bit of a heads up, even though you can pretty much tell from looking at the tread pattern on the tyre
