The S20/21 etc are a more road biased tyre so you can?t directly compare them to the Rosss Corsa as that?s more like the RS11 etc, the Pirelli Rosso 3 and now 4 would be a better comparison to the S21/22. I?ve ran both on track and ran both on my previous bikes, 1299s and GSXR 1000. I?ve also ran the R11?s, RS10?s etc and they?re all good.
The BT016 was a pish tyre especially the front, always ended up shaped like a 50p coin.
That reminds me of a joke.
This Dads at home all happy because his daughter has just married a millionaire, next thing the door goes
So he goes and answers it and here?s the daughter standing with her bags crying like buggery,
?what?s up?
daughter says ?I?ve left him dad?
?what do you mean you?ve left him, he?s a millionaire ffs?
?well, before we were married my bum hole was the size of a 1p coin and now we?re married it?s the size of a 50p coin?????.
?what, you?ve left him over 49 fookin pence?????..
