Bridgestone 21250 Battlax Racing Street RS12 Hypersport Motorcycle Tire

The Bridgestone Battlax Racing Street RS12 represents the pinnacle of hypersport tire technology, bringing race-proven performance to both street and track riding. Engineered under the concept 'From Circuit to Street,' this DOT-approved tire delivers race-level grip without requiring tire warmers, making it the ultimate choice for riders who demand maximum performance on track days while maintaining street legality.

Advanced Race-Derived Technologies:

• Features a new racing compound, optimized tread pattern, and the revolutionary HE-MS Belt (High Elongation Mono Spiral belt) structure—a first for a production street-legal tire
• Utilizes 3LC compound technology with a harder center for extended road life and softer shoulders for maximum mid-corner grip and stability
• Optimized groove ratio delivers superior grip performance through enhanced tire rigidity and increased contact area during cornering
• Incredibly quick warm-up performance—ready for aggressive riding in as little as three-quarters of an out lap with no tire warmers required

Performance Benefits:

• Outperforms the previous RS11 model and even surpasses the Dunlop Sportmax Q5 in dry conditions during Bridgestone testing
• Maintains high grip performance even after multiple laps through optimized compound, tread pattern design, and structure
• Offers exceptional grip and feedback while maintaining impressive wear resistance for extended usability
• Delivers stable and predictable braking performance whether straight up or trailing into corners

The RS12 is designed for serious sport riders, track day enthusiasts, and racers who want a tire they can ride to the track, push to the limit during multiple sessions, and confidently ride home. This tire provides safety, peace of mind, and enjoyment across a wide range of riding conditions—from spirited street riding to demanding circuit tracks.
