BATTLAX HYPERSPORT S21 150/60 ZR17 M/C 66W Rear Radial Tubeless Type

【BRIDGESTONE MCR05186 BATTLAX HYPERSPORT S21 150/60 ZR17 M/C 66W Rear Radial Tubeless Type Motorcycle Tire On-Road Sport Circuit Race】
【The view of your usual corner will be transformed】

・The S20 EVO, which has been supported by many riders, has evolved further.
・It surpasses the S20 EVO in terms of easy handling due to its excellent agility and ground contact feel during cornering.
・The rear tire was developed utilizing Bridgestone's proprietary ULTIMAT EYE technology, and by adopting a dedicated compound, traction has been improved and wear life has also been successfully extended.
・A true premium sport radial that further enhances machine performance and pursues the joy of control.
Recommended for customers who:
●Primarily enjoy sport riding
●Seek both wet performance and wear life for their supersport vehicle
●Are considering starting circuit riding
【New Front Tire Shape】

By reducing the crown shape of the front tire, 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 force that turns the vehicle (camber thrust), contributing to improved agile cornering performance.
【Dedicated Compound Adoption】

We have re-examined the compound design from a molecular level and developed a compound that improves the contact between the tire and the road surface at a micro level. This compound is used in the shoulder areas of the front and rear tires, which are crucial during cornering, 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 running conditions.
Traditional tire development has followed a process of simulation, prototype creation, indoor measurement, and performance verification through actual vehicle testing. ULTIMAT EYE can reproduce high-speed driving conditions equivalent to actual vehicles indoors and visualize the behavior of the tire's contact patch. This allows for highly accurate analysis and performance verification based on scientific evidence, in addition to traditional actual vehicle testing. The testing machine 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, we succeeded in accurately understanding the slipping behavior of the tire on the road surface at the contact patch, which was not visible with previous analysis techniques, and significantly reducing the slipping area. This reduced wear and achieved approximately a 30% improvement in wear life.
【Unique Tread Pattern Design】

・ The three-dimensional groove ends increase tread rigidity, improving corner grip.
・Lug grooves extending beyond the center line optimize the rigidity of the center tread, improving road contact and agility.
・Rib blocks in the center of the rear tire suppress slipping and extend wear life. (ULTIMAT EYE)
・The shoulder area features a slick groove arrangement, providing a large contact patch and improving corner grip.
