This 190\/55ZR17 tire carries a 73W speed rating and is engineered for speeds up to 168+ mph when properly fitted and operated according to the motorcycle and tire manufacturer’s recommendations. Bridgestone combines responsive handling with consistent road contact to help riders maintain confidence through acceleration, cornering, and braking.\u003cbr\u003eThe Battlax Hypersport S21 uses Bridgestone’s Enhanced Micro-contact-patch Compound (EMC) technology in the front and rear shoulder compounds. This compound design increases grip potential while improving thermal stability, helping the tire maintain consistent performance as operating temperatures rise. Dry grip and wear life are significantly improved without sacrificing wet-weather performance, making the S21 a balanced option for riders who need sport-focused capability with predictable behavior in changing conditions.\u003cbr\u003eThree-dimensional cross grooves are designed to optimize tread rigidity and improve contact with the road. This helps support stable handling, controlled feedback, and efficient use of the available contact patch during cornering. As a rear application, the S21 is suited for motorcycles requiring a high-performance sport tire that can deliver strong dry-road traction while preserving practical wet-road capability. The Bridgestone Battlax Hypersport S21 rear tire is identified by manufacturer and vendor part number 9343, providing a direct reference for fitment and product selection. Always verify the recommended tire size, load capacity, speed rating, and compatibility with your motorcycle before installation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eEnhanced Micro-contact-patch Compound (EMC): Increases grip potential and improves thermal stability for consistent performance as temperatures rise.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSport performance: Improves dry grip and wear life without sacrificing wet-weather performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e3D cross grooves: Optimize tread rigidity and improve contact with the road for responsive handling and controlled feedback.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpeed rating: W-rated for speeds up to 168+ mph under proper operating conditions.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Rear motorcycle tire designed for sport and hypersport riding.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProduct identification: Bridgestone Battlax Hypersport S21, 190\/55ZR17 (73W), manufacturer and vendor part number 9343.\u003c\/li\u003e\u003c\/ul\u003e","brand":"BRIDGESTONE","offers":[{"title":"Default Title","offer_id":49388406407403,"sku":"03040252","price":285.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/56863.png?v=1789028561","url":"https:\/\/ctracingservices.com\/products\/bridgestone-battlax-hypersport-s21-rear-motorcycle-tire-190-55zr17-73w-part-number-9343","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
