HYPERSPORT S21

PAIR DEAL
120/70-17 (58W) + 180/55-17 (73W)

 

Your favourite corner will look completely different

The S20 EVO loved by so many riders has evolved again

Due to its superior agility, the S21’s ease of handling and the contact feel when cornering surpass even that of the S20 EVO

The rear tyre was developed with Bridgestone’s new ULTIMAT EYETM technology, while the new compound succeeds in generating better traction and while improving abrasion resistance for longer life

This marks the birth of a new premium sports radial, one that brings out the best in machine performance in pursuit of the joy of riding

The Thrill of riding in any conditions

S21 is an awesome mix of the proven wet technology of S20EVO and radical new features that take dry performance to a whole new level

Extreme cornering

The superior stability of S21 allows higher entering speeds, a sharper line and faster exit – giving you a feeling of confidence and achievement through corners

High mileage

You don’t have to trade life span for top handling performance. S21 clocks up to 36% higher mileage than its predecessor

No compromise on safety

Bridgestone’s advanced tread pattern and compound technologies give you all the reassurance you need in the wet

FEATURES

Advances in compound development at the molecular level upgrade adhesion and grip for faster cornering and higher confidence

Front tyre: the smaller crown profile gives a longer contact patch and better pressure distribution for improved handling and precision

Rear tyre: the larger crown profile together with optimized belt construction and groove positioning upgrades rear feeling and increases cornering stability

3-layer compound (front) and 5-layer compound (rear) plus high-stiffness bead filers give optimum damping and stability

Pattern with 3D groove ends, optimized groove layout and almost-slick shoulders designed for stability and handling with consistent high grip

Battlax S21 is the first tyre to benefit from Bridgestone’s new “ULTIMATEYE” indoor testing facility which analyses tyre behaviour at the point of contact

MS・BELT Mono Spiral Belt

Lightweight and durable cords are wrapped around the circumference of the tire to provide a smooth grip feeling. This contributes to a high performance tire with ①weight reduction, improvement in ②grip improvement, ③rotational stability, ④high speed performance and ⑤excellent damping effect.

 

HTSPC High Tensile Super Penetrated Cord

Steel cord material is comprised of individually rubber insulated inner filaments with high thermal conductivity to enhance heat transfer and reduce the risk of blowout. Moisture does not accumulate between filaments, reducing the chance of oxidation. The features promote high speed stability and durability of the tyre as a whole. High case rigidity (grip performance) and superior shock absorption have also been achieved by these highly tensile filaments which have strong resistance to deformation.

3 Layer Compound

3LC (3 Layer Compound) technology.
The shoulder compound provides excellent cornering grip. The centre compound offers linear handling.

 

5 Layer Compound

5LC (5 Layer Compound) technology.
High grip performance has been achieved for every sports racing scene. The edge compound improves rotational stability during steep banking. The shoulder compound improves cornering power and grip performance in the forward direction. The centre compound achieves a smooth feeling from straight runs to lean angles.

The compound with the highest “tensile rigidity in the circumferential direction” is used in the shoulder area, enabling rapid acceleration at a corner exit.

 

ULTIMAT EYE™

Bridgestone’s proprietary tyre development technology for measuring and visualizing tire contact surface behavior during actual riding conditions. Previously, tyre development consisted of running simulations, building prototypes and using laboratory measurements as well as actual vehicle tests to verify performance. ULTIMAT EYE™ reproduces high-speed riding conditions in the laboratory that are equivalent to those of an actual vehicle, enabling tyre contact surface behavior to be visualized. In addition to the previous actual vehicle tests, this allows high-precision analysis and performance verification with a solid scientific basis. Using technology born to develop tyres for the world’s most demanding car and motorcycle races, the measurement and analysis equipment can handle speeds of up to 400km/h and lean angles of up to 60 degrees.

What A Great Tyre
Fitted these up to my VTR 1000 yesterday and went for a scrub in ride.

I have just come of some Bridgestone T30 tyres that gave me excellent service achieving over 9000Klms under a wide range of conditions from thrashing over my favourite mountain to long distance touring.

I thought that the T30 was a great tyre until I sampled the T21s.

The grip level has to be experienced to be believed, the bike tips into corners soo much easier and seems to ride smoother.

All in all these tyres are coif dense inspiring and even if I don't get the mileage out of them like the T30s I will be happy as the bike is much more settled and tracks and rides so much smoother.

I am very impressed with the way they ride over rough surfaces , the bike just feels so much more responsive.

Big WOW , I didn't think that a tyre could make such a big difference to the way the bike now steers and responds.

I am glad that I took the recommendation of the folks at MCTW as these tyres are a big confidence booster and make riding the bike at it's upper levels so much better.

Try these out, I'm sure you will be as impressed as me.

Once again I am a very satisfied customer (This is the 5th set of tyres I have purchased from these folks )and appreciate the service and advice.

Long Life
After having the S21s on for 7'months and clocking up over 5000k I can now confidently say that these are a worthy tyre.

All sorts of conditions even some dirt riding and they are about half worn. The good thing is that they are still feeling good and haven't lost any of their performance.

I am very happy with these tyres and will replace with the same when the time comes.

At this stage it appears that I will get the same sort of mileage that I got out of the t30s that they replaced.

Another World
So firstly ive been riding for 3 years and ive been riding my Triumph Street Triple for over a year of that.
I got about 23,000klm out of a set of Pilot Road 2's (yes you read that right) which came with the bike and they were fantastic to learn road riding.
And after touring, commuting and 2/3 track days on those tyres I was ready to pick my first new set of rubbers haha.
So after countless hours online watching reviews I found myself finding the S21's were perfect for what I needed (street riding w/ track in mind). So as you might have guessed I have picked up a set and did 200klm in the first day I got them fitted and fell in love.
Extra grip and the confidence knowing that I can use them every day and nothing funny is going to happen.

Defiantly would recommend to anyone looking for a street tyre with more grip without forgetting that you use the damn things every day for riding or work or blasting around the hills on the weekend!

Well still Ill be interested to see how long I get out of my S21's but Im hoping to move on the Trumpy before I need to fit another set
