Incorporating Racing Tire Technology to Deliver Superior Dry Grip Performance

NASHVILLE, Tenn., Oct. 30, 2025 /PRNewswire/ -- Bridgestone Corporation (Bridgestone) today announced that it will launch the premium sports motorcycle tire BATTLAX RACING STREET RS12 in January 2026 for North American markets. Under the concept of 'From Circuit to Street,' by incorporating race tire technology, BATTLAX RACING STREET RS12 delivers the highest level of dry grip performance in the road-legal tire lineup of BATTLAX.

Key Technologies Featured in the BATTLAX RACING STREET RS12

1. Compound
   Equipped with a compound engineered from technologies advanced through racing tire development.
   
   
2. New Tread Pattern
   Newly designed pattern with an optimized groove ratio delivers superior grip performance¹ through enhanced tire rigidity and an increased contact area during cornering².
   
   
3. New Structure
   For the front tire, the HE-MS BELT structure, proven in the world's top-level motorcycle races, has been adopted for the first time in a commercial BATTLAX tire. This flexible belt equalizes contact pressure to further enhance grip.

Incorporating technologies proven through continued success in motorcycle endurance races, BATTLAX RACING STREET RS12 delivers comprehensive improvements in circuit performance, with a particular emphasis on dry grip³. Lap times are reduced significantly compared to the previous model, BATTLAX RACING STREET RS11³. In addition, by optimizing the combination of its compound, tread pattern design and structure, the tire maintains high grip performance even after multiple laps³. As a result, it provides riders with peace of mind and enjoyment across a wide range of riding conditions—from sporty riding on dry roads to winding roads and circuit tracks.

Bridgestone is committed to supporting the development of a safe and enjoyable motorcycling culture, offering peace of mind by advancing a global premium niche strategy utilizing Dan-Totsu products⁴ like its BATTLAX brand premium motorcycle tires. Through these efforts, the Company strives to achieve the corporate commitment of 'Emotion: Committed to inspiring excitement and spreading joy to the world of mobility' described in the 'Bridgestone E8 Commitment'⁵.
