The Bridgestone Battlax R11 is a DOT-approved, high-performance track and competition tire engineered for supersport and hypersport motorcycles. It's designed for racers and track day enthusiasts seeking to improve lap times. The R11 offers enhanced grip, corner entry, braking, and acceleration compared to its predecessor, the R10.
This tire utilizes a very soft compound, indicated by its UTQG treadwear rating of 40, to deliver maximum grip on the track. Bridgestone recommends using tire warmers to optimize performance and ensure even wear, especially when freshly mounted.
The Battlax R11 incorporates Bridgestone's Variable Mono Spiral Belt (V-MSB) construction. On the front tire, the belts are spaced closer in the center and further apart on the shoulders to improve contact patch pressure during cornering, enhancing front-end feel and rider confidence. The rear tire features a V-MSB construction tuned for optimal deformation, along with an additional GP belt (also found on Bridgestone's V02 racing slicks) to stabilize the tread and increase drive grip. The tread pattern is designed to maximize rigidity during cornering and contact during acceleration, while also optimizing warm-up times.
Compared to the R10, the R11 provides more consistent performance throughout its lifespan. Bridgestone's Ultimat Eye technology was used to analyze the tire's behavior under stress, optimizing the design for enhanced grip and stability. The R11 is available in a range of sizes to fit various sportbikes, from small-displacement machines to superbikes. It is available in soft and medium compounds, depending on the size.
