Hey everyone, I just picked up a new (but old) Pirelli Supercorsa. It’s a rear (140/70) and was made late 2018 (date stamp 4018). It was given to me by a friend who is taking a break from riding but he forgot what compound it is. It doesn’t have the typical SC1/2/0 stamp on it, wondering if it was just an automatic SC1 since I think that’s when they first started making these tires in the smaller displacement bike sizes? Attached pics for reference.
