I go these for my R1M and installed them last week, have had a chance to throw them at a few corners and live with them a bit since. I absolutely love the RS10’s that bike came with, but this would have been the 4Th RS10 on the rear in the 8,500 miles since I bought it-switching to the S22’s wasn’t a matter of cost, it was because of the hassle of going thru them that often.
I put a set of S21’s on my GSXR1000 3 years ago and was immediately impressed with how good grip was when cold and the wear rate has been really, really good. I ride my R1M pretty hard with a fast group of guys out on country rides, so getting away from the RS10’s I trusted so much was a big gamble considering how long they would last before needing replacement. The S22’s feel stickier than the S21’s, and the steering is notably lighter than the RS10’s. I run the pressures in the 36-37PSI range like on the RS10’s and it really helps with wear and flat-spotting. These tires feel stiffer than the track oriented RS10’s and at similar pressures you get less flex to communicate what the front is doing-not a bad thing, but it took a little recalibration to have the same trust I had in the RS10’s.
Like the S21’s, these seem to warm quickly and I generally don’t have to give a lot of thought to getting heat in the tires before getting “on the wick”.
I still have 30-40 percent of life left in my 3 year old S21’s on the Suzuki, these should last about as long and I don’t feel like they are holding back my riding pace at the level I ride at. I would absolutely do a track day on these!
Bottom line is that you can do a lot worse than these tires, they would be a first choice for me when the time comes to replace the S21’s on the Suzuki. You’d have to be pretty fast on track to need better tires than these, and then you’d have to live with the same tire life issues I did with the RS10’s.
