S22 was a major leap forward over the S21, better grip, longer lasting, better feal, better tip in, etc. Thats why the S22 has won the Motorad sports tire of the year twice. Conti Road Attacks would be my choice if i wasn't doing track days, amazingly good tires.I mean this in the nicest way possible...but who gives a ****? This bike gets about 3,ooo miles per tire (actually less than 2,500 for me with the S21, but whatever). If a tire that got 3,600 miles performs like hot garbage you're saying you would keep it over an amazing tire that gets 3,000 miles? Am I hearing that right?
The S21 and the S22 are not in the same league.
