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.

Dry Grip - never had any drama or issue's. They were flawless, however never gave a feeling of security, likely due to the harder compound and vague feedback.

Wet Grip - very poor for the type of tyre this aims to be. I found that I would often have "oh sh*t" moments with these in the wet, and frequently it'd feel like I was going to lose the front even at a slow pace. Look elsewhere if you want good wet weather performance.

Road Feedback - I felt these offers poor feedback until they were on the edge of grip. They hardly let you know what is going on until they are starting to slip. In the wet for example, they do not communicate anything until they are starting to slip. At this point however, they actually communicate quite well.

Handling - these tyre's tip in nicely and are quite predictable once you get used to their numb feedback, as they are very consistent tyre's.

Wear - very disappointing for sporty commuting tyres. I got just over 5k at the rear when I needed to start thinking about replacing them, was barely 1mm off of the minimum depth indicator, on a sub 140kg 125cc with 15hp... Not impressive at all.

Comfort - not amazing but not bad, feels overall like a pretty stiff tyre but isn't outright uncomfortable.

Buy again - personally, I was looking at getting different tyre's near enough the whole time I had these on my bike. I wanted something with more confidence, the only thing that stopped me was the fact I was going to be selling the bike and wouldn't get my money's worth out of a new set. The 100/80/17 130/70/17 sizing of my bike's tyres also made it difficult to find many higher end tyre options. But I wanted to get some Pirelli Diablo Rosso III's. However, for the price and how much grip they have in the dry, as well as they relatively playful handling, these are definitely the not bad.

Fitted to a Honda NT 650 - fine if not brilliant in the dry but slightest hint of moisture on the road and they squirm around like a snake - utterly deadly in the wet. Lasted 4000miles on the rear and 5500 on the front - not impressive at all and I'm pleased to be rid of them. They seem to absorb road deviations pretty well but are particularly noisy on all surfaces.

These tyres are decent in fine weather, and I have had no issues with response, feedback, wear or anything else. However these tyres can easily get you killed in the wet. Very poor wet grip and can be felt slipping quite easily. If it never rains then maybe get these tyres, but you ride in the rain then please do not use these. It’s not worth your life.

Just fine on dry pavement. But go super easy in wet weather. At 35 km per hour with no throttle or brake input they slid out from under me in a tight but steady corner in the wet. No warning.

Lowsided on wet road, totaled the bike. Felt like it was a good tire until it wasn't. This tire cost me more than any other tire would. Wasn't going fast, but it was still to fast for this tyre.

When the road is hot the grip is indeed the best, but when it rains it is a bit dangerous

Excellent

Honestly I see a lot of bad reviews for the Tyre. I can’t really fault them myself.
I've had them on my ninja 250 for a bit over a year and 11,000km later they still look new with a good profile, no squaring or anything. The smallest tread depth is on the front with 1.9mm to go until the wear bars. 2.5mm on the rear.
PS tyre size on the rear is a 140/70.17 my tyre size isn't listed.

I have had one worrying moment in the dry where I felt the front slipping, but it gripped back after what felt like sideways ABS. Road surface was smooth, warm day and I didn't see anything on the road on that pass or on inspection the following day. I was riding briskly but not pushing it.
No faulting wet weather performance, in fact it feels better in the wet than in the dry (though I ride more cautiously)

I regularly mess around breaking traction when its safe to do so, to see where the limits line. When I try endo's/stoppies I lock up 50% of the time, 50% of the time I lift the rear wheel, that seems good enough for me - rear wheel off the ground in my last rainy ride.
I'm definitely not a super fast rider (1cm chicken strips and my knees are still intact) but I do ride aggressively in a spirited manner. I mostly use my ninja to commute (on twisty country roads), hence the upright riding.
My other bike is a Street Triple 675 hence not using the ninja to its maximum capabilities.

Terrible tyres. I normally get 15000 km from a set. These hit the wear marker at 5500 km. Now I've done 6500 km and they are almost slicks.

They do grip well and I can lean the bike with confidence, but they are not half the price of Michelin Pilot 4s which have lasted me well over twice the km these pieces of shut did.

If you have enough money you should buy better tyres.

Changed front & rear Pilot Street (non radial). And been riding for 3 months now. Dry grip is ok. Not good but usable under normal riding. But if push these tyres a bit more, then u will wish u spend a little more for a better tyres. Wet grip is unusable, quite slippery n not as expected or advertised by Michelin. Straight road is ok. But very slippery in wet condition in corners. Just need to slow n keep most upright at the corners on wet roads. I regreted buying them as I feel my life is worth much more then these tyres. Need to ride slowly n carefully at the meantime. Save up money to change these Michelin tyres. Never again I shall buy another Michelin tyres.

A truly dreadful tyre they wear uneven making them dangerous on anything faster than a push bike
I have done around 500 miles on these tyres and kacked my self on every corner
They wouldn’t warm up in the Sahara never mind in old blitty
Pay a little more for pilot power

Truly dreadful tyres. Whilst they are a good grippy tyre in wet and dry the manufacture is desperately poor.
The Michelin Pilot Street front tyre 2.75 18 had such a bulge or offset moulding the bike could not be ridden faster than 25mph without massive vibration and the handlebars banging up and down. The rear Michelin Pilot Street 90/90/18 was only marginally better. As a new biker it took me a while to discover what the problem was. It never occurred to me that tyres could be so mishapen.
My replacement Continental tyre is perfectly formed and smooth as silk.
