Battlax Hypersport S21 130/70 ZR16 M/C 61W Front Radial Tubeless Type

【BRIDGESTONE MCR05184 BATTLAX HYPERSPORT S21 130/70 ZR16 M/C 61W Front Radial Tubeless Type Motorcycle Tire On-road Sport Circuit Race】
【The view of your usual corners will be transformed】

・The S20 EVO, which has been supported by many riders, has evolved further.
・Its ease of handling due to its excellent agility and the feeling of grip during cornering surpass the S20EVO.
・The rear tire was developed utilizing Bridgestone's proprietary ULTIMAT EYE technology, and by adopting a dedicated compound, traction is increased, and wear life has also successfully improved.
・A true premium sport radial that further brings out machine performance and pursues the joy of control.
Recommended for these customers:
●Customers who mainly enjoy sport riding
●Customers who seek both wet performance and life performance for their supersport vehicles
●Customers who 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 front-rear direction of the vehicle. This increases the force that turns 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 contact between the tire and the road surface at a micro level. This compound is adopted in the shoulder areas of the front and rear tires, which are important during cornering, improving cornering grip performance.
【ULTIMAT EYE】

Bridgestone's proprietary tire development technology that measures and visualizes the behavior of the tire's contact patch in actual driving conditions.
Traditional tire development has followed a process of simulation, prototype creation, indoor measurement, and performance confirmation 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 confirmation based on scientific evidence, in addition to traditional actual vehicle testing. This testing machine for 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 grasp the sliding behavior of the tire on the road surface at the contact patch, which was not visible with conventional analysis technologies, and successfully reduce the slip region significantly. This reduced wear and achieved an approximately 30% improvement in wear life.
【Original Pattern Design】

・Three-dimensional groove edges increase tread rigidity and improve cornering grip.
・Lug grooves extending beyond the centerline optimize the tread rigidity of the center part, improving road contact and agility.
・Rib blocks in the center of the rear tire suppress slipping and improve wear life. (ULTIMAT EYE)
・The shoulder area has a slick groove arrangement, providing a large contact patch and improving cornering grip.
