Bridgestone Battlax Hypersport S21 Rear Tires

The next evolution of the Hypersport S20, the Bridgestone Battlax Hypersport S21 Tires have been totally redesigned, taking the already stellar performance of the S20 to a new level. Using Bridgestone's in-house UltimatEYE technology to measure and visualize the tire's contact patch and behavior at varying speeds, lean angles and conditions, the Hypersport S21 makes marked leaps in stability and high-speed performance. The three-compound construction rear tire is one of the first of its kind, increasing lean angle contact patch and delivering unrivaled performance in extreme conditions. Combined with a two-compound front tire, the Hypersport S21 boasts an entirely new profile for greater stability and a 36% improvement in mileage. 

Whether you are a track day enthusiast or just need a tire to grip it and rip it through your favorite back roads, the Bridgestone Battlax Hypersport S21 Tires are designed to match the performance of the latest generation of super sport motorcycles. 

Features:

  • Dry grip and wear life significantly improved without sacrificing wet performance
  • 3D cross grooves designed to optimize rigidity and improve contact with the road
  • Dual compound front tire (3LC) with revised profile generates higher grip at lower lean angles
  • 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
  • Tubeless (TL)
  • Blackwall
  • (W) - rated for speeds up to 168+ MPH

S21 GREAT TIRE
Just did my first aggressive weekend in the mountains and the lean angle and stickiness of these tires are great , coming from the M5 and Q3's that are great tires but lack longevity and only time will tell with these .. I don't feel the pavement as much as expected so the feel is not great but I did feel safe at full lean (no chicken strips)
Haven't been in the rain and unless I get stuck in a freak rain storm I never will since I ride a Superbike so can't talk about how they are in the wet ..
Milage I'm sure won't be great but I ride a 1000RR and tires usually last me 1800-2100 miles( rear )so anything in that milage range I will be happy ..
I was lucky enough to get a great deal for a set and paid 229$ shipped to my door ..

The only problem with the new S21 is trying to find video reviews of them since revzilla only has the video for the S20 not the S21 and YouTube only has 2 vids and they are in Spanish lol .. so far great tire and the price is great ..

So far so good!
Bought them and installed them recently, but I've already logged over 500 miles. I'm coming off a few Dunlop Q3s which set the bar pretty high and the S21s seem to be keeping pace. Ran them at the 1/4 mile with 38 psi and cut a 1.8s to 60' on my 505 lb "touring" bike. I have a track day at NCBIKE coming up, so I'll see how they do there. On my preliminary testing on parking lots and twisties, I've been taking the tire to the edge and they feel grippy and steady. My only hope is that the rears last me over 3000 miles!

Better than expected and holding up well to track duty
My Daytona 675R had a brand new pair of these on it when I bought it used. I have only tracked the bike minus a few road rides since owning it. Jennings GP in N. FL has a notoriously rough surface that eats soft rubber tires like Pirellis for breakfast. I've done 4 long days at the track and I can probably do 4 more. I can't believe they are holding up this well. I talked to the tire guy there and he was surprised. I have not exceeded their grip limits either. The front has a slightly vague feel to it, but other than that I am completely shocked at the longevity per grip ratio. Tip in is nice as well, I run an intermediate pace and use tire warmers on low just for the 1st lap piece of mind. Warmers are not needed. PSI: Cold 26/29 Hot off track: 32/31 These pressures have shown perfect and even wear w/ no cold or hot tearing. Thinking going to 29 or 30R hot off track to see how that works for a little more contact patch. Could be a Q3 killer. Street performance and rain I can't really say. I'm sure they are fine on street but rain?? If you can't out pace a tire and keep enough heat in it by going really fast don't waste money on DOT or pure race tires. I think these tires would suffice anyone into the mid/upper intermediate level riders on middle weight bikes.

Great track/road tire
This review is for the front/rear combo, not just the rear. I got these after using the Dunlop Q3's. The S21 is very stable in corners and handles bumps extremely well. I like the front over the Dunlops, but I like Dunlops rear more. I felt I had just a bit more grip leaned over on the Q3's rear during track days. I had the S21 rear step out on me more than I preferred, but the front tire gives so much confidence. So if you're one whose style is to put a heavy load on the front this is a great tire choice. Tire wear has been extremely good for this class of tire. They should last a while on any 600/750 class bike.

Can't beat them for the money
So far the tire is great! Nice deep tread appears that it has lots of wear available. Tire is nice and grippy in the curves (triple compound!), and feels very neutral. The only thing I've noticed is, during hard straight line acceleration I have had some tire slippage. This is in summer heat, with the tire nice and warmed up. This is probably due to the harder center, but is worth noting. My bike has traction control, so I notice the light come on, but I can't really feel it. Otherwise great tire, and I highly recommend it for spirited street riding. Especially when paired with the matching front, which is an amazing tire also. Tread life is yet to be determined on my torquey Ducati Monster.

From Supercorsas to the S21
I was very tempted to follow the masses and buy the Dunlop Q3's, I'm very glad I didn't. My mechanic recommended them and I didn't think I could get as good of grip coming from the Pirelli Suppercorsas. So far with these tires the grip is great, they heat quickly and are slow to wear. The only complaint I can think of is that more input is required for corner turn in. Once laid over you get excellent feel and great grip. Highly recommend especially at the price point and with a factory rebate.

2200 miles look great
I've ridden these on my gsxs750 for about 2200 miles now. They are holding up well and do not show much wear. I am hoping I can get 6k miles. They hold a line and glue to the pavement. I live in a hilly twisty area and have put these tires through their paces. I have been stuck in a thunderstorm with these, the speeds I was traveling at were too slow to really know how well they'd take a turn. No issues so far.

Great tires, had the previous version, the s20's, and they were pretty good, but these ones are amazing. I haven't gone to the track with them, but I'm waiting for the summer to come and I'll let you know how they perform.

Fits my mission perfectly
Doesn't give the same drive off the corners at the track then a Q3 might but, of course, that isn't what it's designed for. I have about 1200 miles on the rear and no signs of flat spotting. Accidently got my peg down at the track and didn't low side so I think the dual compound is money. Seemed to like running 30 lbs front and rear at the track although it was a struggle getting them up to race temp. I'm on a '15 R1

Decent tire, but not a race tire
this tire defiantly grips well but to an extent. they don't heat up like a normal hypersport or race tire would, when they get hot they just get squishy they don't get sticky. in turn making it hard to feel the road and adjust for changes like you should be able too. if you don't plan to ride much in the mountains or hit a track , they are great tires but once you start taking tight turns at 80+ mph you will lose traction and slide into the side of a mountain... believe me, I know.

Wanted to upgrade from the s20 evo. I really didn't care for the tire. I heard Bridgestone made significant overall improvements in the s21 so I went for it. 44 Teeth review and others really helped make up my mind as well. I was torn between these, Q3's, and pp3's. The price tag was also a deciding factor.

I did some research. I previously ran the Michelin Pilot and thought they were great, but wanted to try something different. I've always had good luck with Bridgestone on my vehicles, thought I would try them on my bike.

Is the s21 closer to the race spectrum vs. The s20 or s20 evo or closer to sports touring?
Cortney W on Feb 4, 2016
BEST ANSWER: A couple of years ago, Bridgestone labeled their tires as BT-0XX but these days they have changed ther prefix to
R for Race/Track, S for Street, and T for Touring. The difference between the S20, S20 EVO, and the S21 is the latest iteration of the product. Your choice depends on the type of riding that you do most.....
Has anyone had a problem with punctures? I've gone through two continental sport attack 2's and want to try something different
