BRIDGESTONE BATTLAX RACING STREET RS12 Motorcycle Tyres

The BRIDGESTONE BATTLAX RACING STREET RS12 is a premium, road-legal hypersport motorcycle tyre engineered to bring race-developed technology to the street. Designed for riders who demand exceptional dry grip, precise handling and confident cornering, the RS12 delivers high-level performance on winding roads and racetracks.

Building on Bridgestone’s experience in competitive motorcycle racing, the RS12 features newly developed compounds, an optimised tread pattern and advanced front tyre construction. The result is a tyre designed to deliver strong cornering performance and maintain consistent grip through repeated laps on the circuit.

Key Benefits of the Bridgestone RS12

• Race-derived dry grip: Racing tyre development technology helps deliver outstanding grip for demanding sport riding.

• Confident cornering: An optimised tread pattern and increased contact area support grip when leaning into corners.

• Precise handling: Revised tyre construction is designed to improve contact pressure distribution and provide consistent feedback.

• Consistent track performance: The combination of compound, tread design and construction helps maintain high grip over repeated laps.

• Road and racetrack versatility: A road-legal hypersport tyre suited to dry-road sport riding, winding roads and track sessions.

Advanced Tread Pattern for Cornering Grip

The RS12 features a newly designed tread pattern with an optimised groove ratio. By balancing the grooved tread area with the tyre’s contact area, Bridgestone has focused on improving tyre rigidity and increasing the contact area during cornering.

The shoulder and edge areas incorporate a more slick-like design, helping maximise the available rubber contact area when the motorcycle is leaned over. This design works alongside the race-derived shoulder compounds to support high dry grip and predictable cornering performance.

Rather than simply reducing tread grooves, the RS12’s pattern has been engineered as part of an integrated package of tread rigidity, contact area and compound performance.

Racing-Derived Compound Technology

The BATTLAX RACING STREET RS12 uses newly developed compounds informed by Bridgestone’s racing tyre development experience.

Its 3LC (Three Layer Compound) technology combines different compound characteristics across the tread to balance grip and stability.

• Front tyre: The 3LC compound configuration is designed to support strong grip and cornering performance.

• Rear tyre: The 3LC configuration combines high-grip shoulder compounds with additional cap-and-base construction to support tread stiffness and stability.

This compound arrangement is engineered to provide high grip while helping maintain consistent performance throughout the tyre’s service life. The racing-derived shoulder compounds are particularly important when exploiting the tyre’s cornering capabilities on dry roads and the circuit.

HE-MS BELT Front Tyre Construction

One of the RS12’s key technical advances is Bridgestone’s HE-MS BELT construction on the front tyre, a technology developed through top-level motorcycle racing.

The belt is designed with greater elasticity to help maintain more uniform contact pressure when the tyre is subjected to high loads, including during hard braking. More consistent pressure distribution helps support stable grip and confident front-end behaviour when approaching and entering corners.

Combined with the revised compound and tread pattern, this advanced front construction contributes to the RS12’s focus on precision, control and dry-weather performance.

Designed for Road and Racetrack Performance

The RS12 brings Bridgestone’s circuit-to-street approach to a road-legal hypersport tyre. It is suited to riders who enjoy spirited riding on dry, winding roads and want a tyre capable of delivering high levels of performance during track sessions.

Its integrated compound, tread and construction package is designed to maintain strong grip over multiple laps, making it a compelling option for sportbike riders who value dry grip and consistent cornering performance.
