Bridgestone 22148 Battlax Hypersport S21 Rear Tire 150/60R17 66W

The Bridgestone Battlax Hypersport S21 is an ultra-high-performance radial motorcycle tire engineered to extract maximum performance from modern sport bikes. Building on the acclaimed S20 EVO platform, the S21 delivers meaningful improvements in dry grip and wear life without compromising wet-weather performance.

Key Features:

• Triple Compound Rear Technology (5LC): Three distinct rubber compounds across the tread — a stable center compound, a high-traction shoulder compound, and a high-grip edge compound — deliver confidence from straight-line acceleration through maximum lean angle
• Enhanced Micro-Contact-Patch Compound (EMC): Applied to the shoulder zones on both front and rear tires to increase grip potential and maintain consistent thermal stability as tire temperatures rise
• 3D Cross Grooves: Tread pattern geometry is engineered to optimize block rigidity while improving road contact and water evacuation for reliable wet-weather grip
• ULTIMAT EYE™ Technology: Bridgestone's proprietary rear tire development process ensures precise compound placement and construction consistency
• Radial Construction: Provides superior high-speed stability, precise cornering feedback, and reduced heat buildup compared to bias-ply designs
• Tubeless (TL): Ready for tubeless fitment on compatible 17-inch rims
• Blackwall Sidewall: Clean, classic sport bike appearance
