Unreal tires!
I have put about 2000kms on these tires on my CBR600F4i fully loaded with luggage, empty, rain, dry. These are the first street tires I felt comfortable trail braking into corners when I overcooked things a little. Great feel and so far really good wear, hardly any after 2k! I am running 34psi front and 38psi rear for when I was fully loaded. Awesome tire for the price!

These Stones Rock!!
Bought these as an upgrade to the BTO 16's and were they ever..Better traction for sure.Confidence in corner exit is superb..Great tires..Hope they last a bit longer than the 16's,as my bike has a voracious appetite for rear tires..(05 gixer 1000)..Extremely happy so far..

Great tire for what it is ment for.
I have had it on my bike for about 2 weeks now almost and have put on just over 1500kms on it. I have road in light rain and torrential down poor with 105km/h wind gusts.(not by choice) i am very very happy with it. Is it my first choice in track tire? No but you could still use it there no prob. Where it shines is in the city and on the highways. Grips well and warms up fast. handles well on wet roads with a super sport.(obviously not trying to drag knee). I was still able to drive the speed limit and had never lost traction once in the rain. With the big wind gusts i had to slow down but only because the wind was trying to take me away. On dry pavement in the city it holds great. Run the PSI a little low around 32 and you will hold your line np. Great in cold and hot temp too. Living in Calgary our temps can change drastically at a moments notice. All in all a great tire for its purpose. I would recommend this to anyone that rides a sport bike and wants a great all around tire. Will right more when i have used up the tire and let everyone know how many KM's i got out of it.

Great tire, uneven wear
I put about 10000km on the tires (all on public roads) and they wore completely worn down, should properly have changed them at 8000-9000km.
Was a great set of tires, good confidence, really stable and I could only spin the rear if I was really pushing it, though I did spin the rear a lot when it got wet.
My biggest problem is that the front tire wore unevenly, the hard center looks like it's hardly used, but the softer side is almost worn down, giving the front a uneven curve.
I ride a CBR1000RR with a 190/55/17 rear tire.

Purchased this tire early July,Unfortunately the front was on back order so I am running a BT 016 Pro on the front and the S21 on the rear stock sizes.
This tire sticks really well wet and dry and the wear factor is looking real good .I usually burn thru a Bt 016 in less then 4500 KMS . I presently have around 3000 KMS on the S21 and it hardly looks worn at all. I will mount a matching set of S21's next time around. There are many choices for tires and lots of good one's but my moneys on these Bridgestones

Low mileage
As grip and traction goes it is great tire, even in the wet. But mileage is very poor. Had two sets and the rear would last less than 4 000km. That's kilometers not miles... Got them on my new bike and even with the 1000km bike break in period rear would be done before the 4k mark. I got a second rear and that would last about 3500 km. First rear was always kept on the manufacturer recommended pressure, for the second I was riding about 2-3 psi more, hoping it will help with the tire life, it didn't... I live in the mountains so I get to ride more than just straight and most of my rides are on the twisties, with some rides with my wife in the back and some longer hauls. So if you are an aggressive rider who rides sports bike as it's intended to, don't trust those reviews from people who get 10 000km+ out of them, they probably ride like grannies....

Great Tires
I have had the Pilot Power 2CT and the Pilot Power 3s before and obviously the stock tires. I've also ridden bikes with the Q3 as well. The 2CT I thought was a great tire so naturally when the PP3 I went with that tire. I was very happy with it overall as far as longevity and performance. I also really enjoyed the Q3s, draw back is the life span.
I thought I would give the S21 a shot. Couldn't go wrong for the price. I've gotta say that they have given me more confidence in the corners then the other tires that I used. When you lean, that extra soft layer that is near the edge of the tire, really comes into play and makes a world of difference. I was also pleasantly surprised that when I was caught in an absolute down pour (had to poor my racing boots out when I got home) how great they were. I was on the highway with a 120km speed limit with cars throwing water at me and I didnt feel any hydroplaning or slipping.
I do notice though that the bike doesn't lean over as aggressively as the Q3 or the PP3. So if you're going into back to back turns I just find the transition isnt as quick feeling. Now this could also be my suspension setup but I didnt feel this with my PP3s.
I've put about 3000kms on them so far and 1600km of that was on a trip that was spent a good amount of time on the highway. The tires are still in great shape and have no sign of that dreaded center flat spot.

Questions
Do I go with a non spect version for a 2016 cbr500r?
Yes, the spec tires are a direct OE replacement for the bikes listed in the item details, so you should choose the non-spec option.
You can still choose an OE spec tire for your bike if the tire size matches. The construction of the OE tires are just built specifically for the load and performance of the specific bikes they are listed for

which tire do I choose for 2004 cbr600f41 the e-spec which stated for cbr1000rr or do I use the 180/55zr17 73W?
You would require the non speced version, the regular 180/55zr17
Date published: 2019-01-04
I understand the OE is g spec for my 18 gsxs 750 rear tire. but how is it different to the 73W? other than price?
The G-spec is different in the case that you would want the exact tires that were on your vehicle when it came out of the manufacturer. This is the only difference. They could be marked (OE).

What’s the difference between “j” and “g” spec etc? Thanks
G Spec indicates that it is the OEM tire for Suzuki GSX-S750 2017 and J Spec is the OEM tire for Yamaha R6 2017. You can find this info in the details section of the item.

What does the 73W or 58W means?
It's the speed rating for the tire. A quick google search for tire speed rating will describe it more as there are charts for the rating.

I have a suzuki gsxr 600, should I order the 180 55/zr17 G spec or just the normal 180 55/zero 17 73W?
Zero 17 73w is good if you are an aggressive rider as the load and speed rating is high comparing zr17 G spec.

Whats the difference between th specs? I have a 2013 fz8
not sure what you are asking but if u are comparing the s21 with the s20, then its the compound used to make the tires. S20 uses dual compound where S21 uses triple compound which allows more grip when leaned over.
