The Bridgestone Battlax Hypersport S21 rear motorcycle tire is designed for riders who want strong dry-road grip, dependable cornering performance, and consistent handling during spirited street riding. This 190/50R17 tire carries a (73W) speed rating and is engineered to support speeds up to 168+ mph when properly fitted and operated according to the motorcycle manufacturer’s recommendations. Bridgestone combines advanced compound technology with a performance-focused tread design to help deliver confident control across a range of riding conditions.
The S21 uses Bridgestone’s Enhanced Micro-contact-patch Compound (EMC) technology in the rear shoulder compound. This construction increases the tire’s grip potential while improving thermal stability, helping performance remain consistent as operating temperatures rise. The result is responsive traction during acceleration and cornering, with improved dry grip and wear life without sacrificing wet-weather performance. The tire is built to provide a balanced combination of high-performance handling and practical road durability.
Three-dimensional cross grooves are designed to optimize tread rigidity and improve contact with the road, supporting smooth steering response and stable cornering behavior. As a rear fitment, the Bridgestone Battlax Hypersport S21 complements performance-oriented motorcycles that require precise traction and dependable road feel. Manufacturer: Bridgestone.
