Product Details
The Battlax Hypersport S21 is Bridgestone's entry into the hypersport radial category preceding the S22 and S23, developed as an evolution of the earlier Battlax S20 EVO. It was the first Bridgestone tire engineered using the company's UltimateEYE contact-patch measurement system to refine handling and high-speed stability. It uses a dual-compound front and triple-compound rear construction, one of the first rear tires of its kind at launch, to increase lean-angle contact and grip. In Bridgestone's own testing the S21 delivered a 36% mileage improvement over the S20 EVO along with sharper turn-in and cornering feel. It is a tubeless (TL) radial sold in dedicated front and rear fitments.
