the grip was there once you got them up to temp, but they wear at an incredible rate. i didnt expect loads of miles from them but

Yyre came as OE on my Z1000sx. These are by far the worst tire i have had on s bike for a very long time. No confidence in them at all other than when the bike is being ridden in a straight line except when crossing white lines, then it shakes its head and weaves all over the place.. In the dry I've had the rear lose traction while cornering on more than one occasion Heaven knows how bad they are in the wet. Fortunately I'm a fair weather biker nowadays so haven't had that experience. The rear only lasted 3000 miles. 2999 too many but hey I'm not wasting rubber. Front faired a little better. I'm hating my new bike at the moment and really hope once I've got better tires on it things will improve. Sadly not these S20rs. Dreadful, dreadful tire.

These came with my early 19 Kawasaki Z1000SX. These are without a doubt the worst tires I’ve ever experienced. Unless the road is burning hot and totally smooth you can’t get them warm enough at sensible riding sprees to grip with any level of confidence. Riding in the wet is to be avoided at all costs. Even gentle Leaning in the wet makes the rear slip and twitch. Changing them out at 3.5K. The rear has badly squared off.

good all round tire, I had the s20 evo too which are supposed to be a little bit better. Did 2 track days without any issues, i get around 3-3.5k from a rear tire. cant comment on wet as fair weather rider. another good point is the tire does not really turn square.

Worst expirience with tires ever on my Yamaha R1. Just got it back from repairs and the new tires were fitted(Bridgestone front and rear). It took me a while to switch from my Yamaha R6 to the good old R1 and initially I thought this was the issue. Nop. 3500km later I have to admit it actually IS the tires, especially the rear one.

Warm up time? What? 2-3 minutes of normal driving?!? Or 1 minute of brake-accelerate and left-right sweeping? And guess - you have to do it every time. When you forget to do it, they feel like a plastic, slipping you on the road like you are some kind of a noobie.

Fast turns. What? You don`t like living any more? Try it with this tires. Especially trail braking tech. Slips you gently when you open the throttle on the exit of the turn.

Slow turns. You want to go 50-60kph and drop a knee? Yeah, sure, good luck. At 40 deg lean you have a 50/50 chance that the rear tire will slide for a nanosecond, then find grip again and try to highside you. On my favourite 28km route(mountain climb) I got at least 10 of those situations, even thou I am expecting such bullsh*t from the rear tire.

Highway? Ooooh, you gotta be joking. Pure unstability at 280+. Okey, they are rated for up to 270. Well, guess what, other brands rated for up to 270 don`t have problems at 270, 280, 290 or 300. But this one has. After 130km of highway riding(avg, 200+km/h, ranging 160-300)? Center of the tire was eaten up.

Mileage. Oh, yeah. This brings us to the mileage. At 1000km the wear started to feel. At 2000km it was already clear that this tire was a goner. And I was still wondering if there was something wrong with the bike, or it was the tires.

Feedback? None. You can never tell what the hell is happening and get any idea what to do until it is too late and:
- Option A, rear slips
- Option B, you feel f*cked, that you could go faster on the corner

Dudes, getting owned by a Yamaha VMAX in a 28km chase(by 10 seconds ahead) should give you an indication what tires are these! We should just say that he was not a Bridgestone fan and I was giving it everything I had(which may seem as little, but... no, I never got passed by a VMAX before in my life).

Now I switched to another brand. And the bike stays... how to say it - it never felt better in my hands.

I have to admit one thing - for such a terrible tire it was performing unexpetedly well in wet. Having in mind that it was probably a bad tire choice I did not push the bike over 11 000rpm at any gear during light rains or wet conditions. Barely had a slip, all under control.

Thanks for not killing me, Bridgestone. Thanks for ruining my summer for the R1. Thanks for giving me a horrible 3000-3500km ride expirience - now I know what a tire should NOT do.

The front tire needs alot of work to come up to temperature. Once tires were hot on very twisty roads they are superb.

Cold or just warm they dont feel good.

Wear not great. 2.5k miles they are at end of life.

These were the factory fit tires on my Kawasaki Z1000sx...

They were grippy on a warm summer day with decent tarmac, not so much in less than ideal conditions. They lasted less than 3000 miles and squared off really quickly with just a couple of motorway runs. When squaring in these tires they felt really unstable, almost wobbly!

Avoid unless you do a lot of spirited riding on good winding tarmac :)

These tires came with my bike. Awful grip in the wet, no stability in corners, awful in the cold, no ability to track a line through a corner. From day 1 until the end or the tires the bike just drifted off cornering lines. Horrendous experience with them. In the 3 months they lasted they put my life at risk more times than I can comfortably recount. I ride every day, these tires did not even finish a winter. Tires went bald on the front within 3000 miles. Back lasted a little better. Profile of tire is horribly pointy, leaning in for corners feels like you have 2 positions - upright and falling over. No control or confidence in the tires ability in any weather condition. Even with traction control at highest level these tires span and lost grip daily with only sensible computing levels of acceleration. Do not buy or use these tires. The worst feeling tires I have ever come across. Not only did the front tire go bald but it actually went totally flat for no reason. No puncture no damage, it just wore itself down and gave up.

These tires came as OE on a new 2016 ZZR 1400, they are an excellent all round tire, Very good in the dry and okay in the wet, they give the rider confidence, I will be purchasing the same tires on the next set, the only down side is the wear, they wear out very quickly, barely 2000 miles on the rear and it's nearly done.

I have had a couple of sets of these on my '08 CBR1000RR and they provide awesome grip on track and on road. At full lean with the foot pegs scraping i still feel confident once they are warmed up. A little throttle sensitivity is required in wet/very cold conditions but no more than normal.

With mainly road riding with the occasional track day they will do about 4000km. If you take them on the motorway the centers will be gone in no time at all.

2200 (s)miles Inc running bike in. Fantastic fast road tire. Gives so much confidence. Handles the extreme torque of the ZZR14 with ease. Expensive tire but worth every penny. Have replaced with the same.

I have had these tires since the bike (ZZR1400 2013)was new a year ago. Have now covered 3740 miles, this has included running in period and touring France with some very aggressive riding. Both hero bobs on foot pegs have been ground away indicating level of grip when riding through bends (Love the Napoleon way awesome). I am now going to buy my second pair (always replace front with rear).

As said already, fantastic tire in wet or dry but only lasted about 2000-2500 miles of fast road use

Brilliant tire if you can afford to replace them every 1000 miles.
My S20's are with Bridgestone as I complained that they were almost illegal after 1000 miles of use.
