It's been a while since my last post, but I've put about 1500km on my M7RR now (yes, the weather in Switzerland is not always how I would like it to be for riding). Just wanted to share my thoughts.
Pricing is approx. the same as the Pirellis, but I expected them to last much longer. According to last year's test results, one should be able to put 5-6000km on them, whereas my front Pirelli (front) is gone after 1500km.
I did a short break-in (250km) and did not notice a big difference to the Pirellis. They warm up very quickly and you can ride with confidence and lots of grip after just 1-2km. Since I signed up for a track day in Dijon, France, I tried the track performance as well. They hold up very well and I did not notice and major problems, no big slides or any moments whatsoever. But since I never did a track day with the Pirellis, I cannot really compare the two tires. I guess the Pirellis should offer a little more grip. However, the M7RR wears really well and shows a good wear pattern (suspension was in stock setting in race mode). After about 300-350km on track, there was not much wear to be noticed (although I was a novice on track, my first track day, and hardly pushed the tire to its limits). Knee down was no problem and I felt confident.
Back on the street I can confirm that the tires require a little more effort at turn in than the Pirellis. But the grip seems to be comparable. I run the same level of TC now as I used to with the Pirellis (5 Sport Mode, 3 Race Mode) and did not notice and more interference of the TC than with the Pirellis. The wear pattern looks very good and even. After 1500km completed I hardly notice any wear front or back and my pace is not too slow. Most of my riding is Country roads and mountain pass, so it's a lot of curves and not much straight line. I guess the tyres should last for at least another 3000km, which is far more than the Pirellis!
All in all for me its a win-win situation and the tyres are a bargain compaired to the Pirellis if you compare how long they last. Will definitely not go back to Pirellis, but might try the Bridgestone s20evo next as well.
