The view of the usual corner changes completely by mounting it.

It greatly improves the performance of S20EVO, and is a sharp sport radial tire that you can experience riding technique and machine performance to the road surface without exception and experience sharp cornering.
It is pursuing to raise the grip power and cornering performance of dry road required for sports radial tires and contributes to the enjoyment of rider's riding.

It applies the development technology ULTIMATE EYE for the first time in motorcycle vehicles for general public road riding and it has also been utilized in tire development for the world's best motorcycle race "FIM Road Race World Championship Series, MotoGP Class", and it combines conflicting wear resistance performance in a high dimension with the required grip force in sports riding. As a result, it realized improved cornering performance and wear life approximately 30% compared with the conventional product "BATTLAX HYPERSPORT S20 EVO".

[ULTIMET EYE]
ULTIMET EYE is Bridgestone's unique tire development technology and it measures, predicts, and visualizes the contact surface behavior of the tire.
It performed simulation, made a prototype, and checked the performance through indoor measurement and actual vehicle test in the conventional tire development.
It reproduces the same high-speed riding condition as the actual vehicle indoors, and can visualize the behavior on the tire contact surface.
As a result, it is possible to perform high accuracy analysis and performance confirmation based on the scientific basis in addition to the conventional actual vehicle test, and to improve the performance of the tire further.
The testing machine that performs this measurement and analysis can handle up to 400km/h and bank angle up to 60-degrees.

"Simulation Design"
It performed various simulations on the computer in developing the tire. It designed for optimum tire design and prototype (measures) for calculation.

"New Tire Design Technology"
It reproduces the dynamic behavior of the tire in the actual riding state and visualizes it, in order to confirm the actual performance which can not be understood by simulation alone. It is original technology of Bridgestone.
High speed rotational tire measurement technology: It is possible to measure up to the effect of the pattern detail at high speed rotation which was not known in the past, by developing measurement and visualization technology of ground force distribution of tread pattern.

[New shape of front tire bringing about grip improvement]
This increases the force for turning the vehicle (camber thrust) by reducing the diameter of the crown of the front tire, and the tire contact surface in a state where the vehicle at the time of cornering is inclined becomes longer in the vehicle longitudinal direction, and it contributes to improvement of cornering performance compared to the conventional product "BATTLAX HYPERSPORT S20 EVO".

[It adopts a new compound that improves cornering performance.]
It reviews the compound design from the molecular level, and it developed a new compound that improved tire and road surface groundability at the micro level. It adopts this new compound as a shoulder part of a 3-divison tread only for Rear 150/60ZR17 and 160/60ZR17, which is important for cornering, front (3-division tread) and rear tire (5-division tread), and it contributes to improvement of cornering performance.

[It drastically reduces sliding area, and achieves wear resistance improvement of approximately 30%.]
It succeeded in greatly reducing the sliding area by utilizing ULTIMAT EYE for rear tire structural design, and it is possible to grasp in detail the behavior of the tire sliding on the road surface on the ground contact surface which has not been seen by the analysis technique so far. This reduces wear and achieves approximately 30% wear life improvement. It succeeded in greatly reducing the sliding area, by utilizing it, and in the analysis technique, it is possible to grasp the behavior of the tire on the ground surface which is not seen in detail.

[Creative pattern design]
The groove end portion of the 3D shape increases the tread rigidity, and the shoulder part employs a technology to improve corner grip, such as obtaining a large contact area by a slick-like minimum groove arrangement.
In addition, it is a unique look that is full of imagination as a major feature of S21, and it includes an impressive side design that exaggerates its presence, such as design incorporating playfulness, and tread design that was sharp of "Japanese Sword" motif.
