BATTLAX HYPERSPORT S21 120/60 ZR17 M/C 55W Front Radial Tubeless

【BRIDGESTONE MCR05183 BATTLAX HYPERSPORT S21 120/60 ZR17 M/C 55W Front Radial Tubeless Type Motorcycle Tire On-road Sport Circuit Race】
【The view of your usual corner changes completely】

・The S20 EVO, which has been supported by many riders, has evolved even further.
・It surpasses the S20 EVO in terms of ease of handling due to its excellent agility and the feeling of grip when cornering.
・The rear tire was developed utilizing Bridgestone's unique ULTIMAT EYE technology, and by adopting a dedicated compound, traction was improved, and wear life was also successfully enhanced.
・A true premium sport radial that further brings out machine performance and pursues the joy of control.
Recommended for customers who:
●Enjoy sport riding as their main activity
●Own a super sport bike and demand both wet performance and long life
●Are thinking of trying circuit riding for the first time
【New Front Tire Shape】

By making the crown shape of the front tire smaller, the contact patch between the tire and the road surface, when the vehicle is leaned during cornering, becomes longer in the longitudinal direction of the vehicle. This increases the turning force of the vehicle (camber thrust), contributing to improved agile cornering performance.
【Dedicated Compound Adoption】

We reviewed the compound design from a molecular level and developed a compound that improves the microscopic contact between the tire and the road surface. This compound is used in the shoulder areas of the front and rear tires, which are crucial during cornering, thereby improving cornering grip performance.
【ULTIMAT EYE】

Bridgestone's unique tire development technology that measures and visualizes the behavior of the tire's contact patch under actual driving conditions.
Conventional tire development has involved simulations, creating prototypes, and then verifying performance through indoor measurements and actual vehicle tests. ULTIMAT EYE can reproduce high-speed driving conditions equivalent to an actual vehicle indoors and visualize the behavior at the tire's contact patch. This allows for highly accurate analysis and performance verification based on scientific evidence, in addition to traditional actual vehicle tests. The test machine used for this measurement and analysis can handle speeds of up to 400 km/h and bank angles of up to 60 degrees.
【Rear Tire Design】

By utilizing ULTIMAT EYE in the structural design of the rear tire, it was possible to precisely understand the sliding behavior of the tire on the road surface at the contact patch, which was not visible with previous analysis techniques, and successfully reduce the sliding area significantly. This reduced wear and achieved an approximately 30% improvement in wear life.
【Unique Tread Pattern Design】

・ The three-dimensional groove ends increase tread rigidity, improving cornering grip.
・Lag grooves extending beyond the center line optimize the tread rigidity in the center part, improving road contact and agility.
・A rib block in the center of the rear tire suppresses slipping and improves wear life. (ULTIMAT EYE)
・The shoulder part has a slick-like groove arrangement, providing a larger contact patch and improving cornering grip.
