I have an S1000RR and these tires were very dangerous at first, sliding all over the place. I almost tossed them after 15 laps even after setting the correct hot pressure. So glad Dave Moss was there (no this isn't an infomercial). I have an upgraded Olhins suspension. Dave made a few tweaks, went out came back, I said better. Dave made another tweak, went out and back, I said it's amazing...long story short we left it at that and I run a faster B speed. I believe my pressure is 28f/24r. Tire pressure never stopped the slide it was the suspension setup. Good Luck.
