When every corner, straightaway and braking point tests your skill, you need a tire that matches your ambition. Bridgestone's Battlax Racing Street RS12 tire is the most aggressive hypersport tire in our lineup, engineered for riders who want an impressive street tire that can deliver an exhilarating street ride or track-day performance without having to commit to race tires. Thanks to the integration of a Bridgestone race compound, the RS12 tire delivers impressive dry grip** and confident handling at high lean angles****. Plus, with a design derived from endurance racing tires, the RS12 tire helps to deliver fast, consistent lap times*** that elevate your riding experience.

**Comparison based on Bridgestone Battlax RS12 vs. the Dunlop Sportmax Q5. in tire sizes 120/70ZR17M/C and 200/55ZR17M/C. Results may vary depending on proper tire and vehicle maintenance, surface conditions and riding habits.

***Comparison based on internal testing of the Bridgestone Battlax RS12 vs. the Dunlop Sportmax Q5 after two consecutive five-lap sessions, in tire sizes 120/70ZR17M/C and 200/55ZR17M/C. Results may vary depending on proper tire and vehicle maintenance, surface conditions and riding habits.

Top Features & Benefits
-High Elongation - Mono Spiral Belt helps with stability and equalized contact pressure under hard braking.
-Advanced Race Compound engineered for impressive dry grip, confident handling and consistent lap times.
-Slick Shoulder Design for increased contact patch at high lean angles and for a true racing aesthetic.

Technology Difference
Pulse Groove
Improved water channeling and drainage resulting in enhanced grip and reduced tire slip ratio in wet conditions. Pulse Groove Technology works by combining pulse-shaped grooves with small center deflectors to equalize waterflow, which optimizes waterflow speed compared to a straight groove. Watch our video about Pulse Groove.
MS-BELT
MSB construction means that a continuous single strand is wrapped around the circumference of the tire. This one-piece construction eliminates overlapping of belts, seams, and joints. An MSB tire is lighter than conventional multi-cross belt construction, it also has more stability since it minimizes heat generation inside the tire and gives high shock absorption.
ULTIMATEYE
Visualization of the tire contact patch behavior with measurement and simulation technology. Supplies less slip area for good traction while riding and improves wear life.
Cap&Base
The underlying layer controls tread stiffness, reinforcement and assists with bump absorption.
3CL (Dual Compound)
Provides grip performance demanded in all riding modes. The center compound offers linear handling. The shoulder compound secures high grip and solid contact feel.
HTSPC
Bridgestone was the very first motorcycle tire manufacturer to utilize 1X5 filament rubber insulated steel (MSB) in the manufacture of its motorcycle radial tires. This makes the tire more flexible, provides more stability without a reduction in shock absorption, and minimizes the generation of heat throughout the tire.
RC Polymer
RC Polymer technology optimizes the distribution of silica within the rubber compound and improves tread flexibility allowing greater contact with the road surface in both hot and cold conditions. The reduction in molecular friction also improves rolling resistance, therefore increasing fuel economy.
Outside Bead Filler
The latest generation outside bead filler realizes the ideal sidewall profile analyzed by a finite element method by giving optimum force distribution and rigidity balance.
3LC+CAP&BASE
The CAP&BASE construction divides the shoulder of the compound of the tire into upper and lower sections. By using a high grip compound for the upper section of the shoulder, and a high stability abrasion resistant compound for the lower and central sections, this provides the desired combination of both performance and mileage.
NanoPro-Tech
NanoPro-Tech is the name of a technology that facilitates the realization of the required features in a tire by controlling the material microstructure through structural design at the molecular level. It is one of Bridgestone’s fundamental technologies.
LC (Triple Compound)
Offers ideal grip performance demanded in all riding modes. The center compound provides good stability. The shoulder compound transfers engine power to the road with strong traction. The edge compound offers strong side grip and solid contact feel at deep lean angles.
Silica Rich
Silica Rich Compound provides enhanced gripping capability in wet conditions and low temperatures. It also provides a more consistent and longer lasting grip.
Silica Rich Ex
Performance in wet conditions is improved by increasing the amount of silica compared to conventional SILICA RICH.
