Dry grip is quite startling but sudden break away is a problem. My car is light and powerful but in the wet the tyre still performs well. Wear is OK(ish) approx 12k of mixed cruising and hard driving. These have performed better for grip than the Perelli P6000 that were fitted before but obviously wear rates are higher. The side walls are softer on the Contis too which took a little getting used too.

The most recent owner reviews fitted in this size, in their own words.
Quite good if you want to ride in nice weather. Get rid of these tires if you'd like to ride during wet days as well! I ride on r3 with these tires and I don't feel confident at all with them!
I used to ride honda 125CBR in UK for more then one year, and to be honest, the grip on smaller tires (you know how tires of 125 bikes are) was MUCH BETTER then the grip on my much wider michelin pilot tires now. I've done already about 3k KM with them and had about 4-5 situations when I nearly felt down during wet days (I have really good experience how to ride in rain from UK but these horrible tires surprise me all the time).
If you want to ride just in nice weather - they're ok but still I think it's better to pay little extra to have decent tires, it can save your life, don't save money on it.
If it's possible that you will be catched by rain or you just want to ride during rainy weather - don't even think about buying this, honestly.
