The next evolution of the Hypersport S20, the Bridgestone Battlax Hypersport S21 Tires have been totally redesigned, taking the already stellar performance of the S20 to a new level. Using Bridgestone's in-house UltimatEYE technology to measure and visualize the tire's contact patch and behavior at varying speeds, lean angles and conditions, the Hypersport S21 makes marked leaps in stability and high-speed performance. The three-compound construction rear tire is one of the first of its kind, increasing lean angle contact patch and delivering unrivaled performance in extreme conditions. Combined with a two-compound front tire, the Hypersport S21 boasts an entirely new profile for greater stability and a 36% improvement in mileage. 

Whether you are a track day enthusiast or just need a tire to grip it and rip it through your favorite back roads, the Bidgestone Battlax Hypersport S21 Tires are designed to match the performance of the latest generation of super sport motorcycles. 

Features:

• Dry grip and wear life significantly improved without sacrificing wet performance
• 3D cross grooves designed to optimize rigidity and improve contact with the road
• Dual compound front tire (3LC) with revised profile generates higher grip at lower lean angles
• Triple compound rear tire (5LC) with revised profile provides improved stability and durability
• New enhanced Micro-contact-patch compound (EMC) technology used for both front and rear shoulder compounds
• EMC increases grip potential and improves thermal stability to make sure the tire performance remains consistent as temps go up
• Tubeless (TL)
• Blackwall
• (W) - rated for speeds up to 168+ MPH
