The Bridgestone Battlax Racing R11 Soft is a DOT-approved, track-oriented tire engineered for performance in racing and track day applications. Designed for riders seeking to lower lap times on supersport and hypersport machines, the R11 provides high levels of grip, feedback, and consistent performance. It is suitable for various racing categories, including SSP 300, SSP 600, and SST 1000 championship series.
This tire utilizes a soft compound to maximize grip and traction, particularly in dry conditions. Bridgestone recommends the use of tire warmers to ensure optimal performance and wear, especially when the tires are freshly mounted.
The Battlax Racing R11 incorporates Bridgestone's Variable Mono Spiral Belt (V-MSB) construction. In the front tire, the belts are spaced closer in the center and further apart on the shoulders to optimize contact pressure during cornering, resulting in enhanced feel and confidence. The rear tire features an additional GP Belt on top of the V-MSB to stabilize the tread, increase the contact patch, and improve grip during acceleration. The tread pattern is designed to maintain rigidity while cornering and maximize contact during acceleration, also contributing to quicker warm-up times. The strategic groove positioning enhances tread rigidity and distributes forces evenly.
Compared to its predecessor, the Battlax R10, the R11 offers improvements in corner entry, braking, acceleration, and overall consistency. Track testing has demonstrated faster lap times with the R11. The R11 is designed to provide a larger operating range, allowing riders to maintain consistent performance throughout a race.
