      The next iteration of the Hypersport S20 tire, the Bridgestone Battlax S21 tire delivers everything the S20 offered - and so much more. UltimatEYE development technology allows developers to simulate speeds of up to ~250MPH and 60 degrees of lean angle to accurately visualize the contact patch, allowing them to see exactly how much grip the tire has and implement improvements accordingly. Some of these improvements include a dual-compound front tire, a triple-compound rear, and an improved tread pattern, all culminating in an increase of about 30% in dry grip over the S20 without sacrificing any wet grip. Whether you’re a canyon carver or track day enthusiast, this tire is rated to about 170MPH to give you the best performance when you need it most.
    • Dry grip and wear life significantly improved without sacrificing wet performance.
    • 3D cross grooves designed to optimize rigidity and improve contact with the road.
    • Triple compound rear tire (5LC) with revised profile provides improved stability and durability.
    • New Enhanced Micro-contact-patch Compound (EMC) technology used for both front and rear shoulder compounds. EMC increases grip potential and improves thermal stability to make sure the tire performance remains consistent as temps go up.

    The best I've tried
    Love this rear tire on my streetfighter 848. I have an s21 on front as well and the bike feels so much better than it did with the Pirelli Diablo Rosso tires. I have to watch my speed more because these S21s inspire so much more confidence.

    I have tried a few brands of tires and tire models over the years and it seems that I feel most comfortable and confident on a Bridgestone as far as sport tires go. When it was time to replace my BT-016 EVOs I opted for the newer S21s plus they had a good rebate if you purchased a set.

    I knew what to expect at baseline since I am brand loyal but these tires exceeded my expectations!

    Turn in is great, stickiness is fantastic, and they are very inspiring in how they go about their business helping your carve up the twisty stuff. If you like how Bridgestone tires work for your style then I really think you'll dig these tires.

    Bought my first set of the S21's and I have to say they are my choice of rubber under me now I was a Dunlop fanatic for years until I decide to switch it up for ounce and I'm so glad I did I get amazing feed back on front a rear both in the corners and they give a sense of confidence. They are not necessarily a rain tire but also do well in and rainy situation!

    Great tires! Send me another set!
    Hello all, I've put 1500 miles on my new set of S21's and they seem to check all the boxes for me... (so far at least, I'd still like to do a track day with a new set). They warm up quick and provide predictable turn in, consistent feedback and stability, with very good grip at all lean angles. Braking stability (straight line heavy front brake, as well as, trail braking into corners) is also very good and predictable. These tires offer a huge amount of grip for a street tire and also have good feedback at or near the limit, which inspires confidence. But... as we know, the condition of the pavement, bike set up, skill level, etc. plays a big role in how much grip is available. Always be mindful of what might effect tire grip. Safety first, please. I've been sport riding for 25 years with some track days sprinkled in here and there (I'm into bike control and lean angle), so I've had the opportunity to sample many sets of tires within the top brands over the years. With current high end sport tires I typically get 2000 to 3500 street miles out of a set. After the initial 1500 miles (sport riding miles only) I am impressed at how well the S21's are holding up, especially for the grip that they provide! They look like they could last ~3500, maybe even more! Great tire and great value! Thank You RM for the great deals and fantastic service, please send me another set!

    S21 great tire
    Great tire and you had the best price. This replaces the q3 on my bike and I couldn't be more satisfied. Its very sticky. I've always thought s20s were great and these are supposed to be an improvement. It's on a 13 cbr1000. Just Gabe My son a 99 cbr900 and he thought they were great too and got over 2700 HARD miles. Shouldn't expect much mileage for the type of tire

    Great tires all the same characteristics of Metzler m7 rr , Dunlop q3, and Michelin power 3 tires at a lower price with no compromise in handling or grip with the addition of 3 compound rear tire.

    I like these tires
    I've had a set of S21's installed on my GSX-S1000 for a few weeks and a couple hundred miles. I ride them on the street and have used them at a track day. I like the light steering feel and good grip at 36F, 42R street pressures on the street. The track day had both wet and dry sessions, including a session with one half of the track dry and the other half wet. I ran 30psi F and 28psi R. The S21's felt solid in the wet, the front especially. The rear stepped put once at the transition from wet to dry, but it was controllable. I seemed to be getting better grip than most in the wet conditions. In the dry the grip felt good. Not quite as sticky as the DOT race tires on my R6, but plenty to have fun with. The tires held up well during the track day with minimal wear. Recommended.

    Very impressive tire at a great price.
    Wasn't happy with the feel and feedback I was getting from the set of Q3's decided to try out the S21 and after the first ride of about 300 miles I am very happy. Roads were a little cold and had a slight mist but they handled great.

    How does the S21 tire profile compare to the Dunlop Q3? I like the quick turn of the Q3, the S20's I have used in the past had a slower (flatter) profile.
    Rodger E on Mar 28, 2017
    BEST ANSWER: In my opinion, the turn in is very similar to my Q3. It's a little hard to give a solid opinion, given I have haven't used S21s on the bikes that have (or had) Q3s, but I have S21s on the Ducati Monster, which once mounted almost turned in TOO fast. The Q3s are mounted to my 996, which is set up for just a slight bit of effort to turn in, but is extremely and beautifully neutral once leaned over (could take my hands off the bars and stay leaned). So set up and geometry between the two bikes are different, so take what I'm saying with that understanding. I've used several S20s, and I liked them, but I like the Q3 better than the S20. I was going to get a set of Q3s for the Monster, but Bridgestone's $50 rebate + the normal price differential between them on Dunlop meant I saved close to $70 on a set. I have been very pleased with the road holding on the Monster using the S21s. Now that it has a few miles on the S21s, the handling has evened out, and they provide enough confidence for my wife to scrape the pegs around corners without thinking. I'll be really pleased if we get 4000 miles out of the rear tire, and so far, looks like we're going to hit it. The front will last quite a bit longer. Also, just my observation, but the 160 series on the little Monster looks to have a "V" profile to the tire shape, more than the Q3 did when it was new.

    If price were not an issue, I would probably stick (pun, sorry) with the Q3. I've run several sets across a couple of our bikes, and it is just a truly excellent tire. It does not get the mileage that I need out of our street bikes though, so I've gone to a sport touring tire on them while the Monster and 996 stay shod with hyper sport tires.
