A front-fit sport motorcycle tyre, the Bridgestone Battlax Hypersport S21 F 120/70R17 58W is developed for riders seeking sharp handling and strong grip on road and track-day environments. It is intended for performance-oriented sportsbikes where precise steering response and cornering stability are essential. The tyre’s profile and compound are tuned to offer rapid turn-in and consistent behaviour through varied lean angles.

The tread architecture employs a silica-enhanced mix and asymmetric block arrangement to boost wet grip and water evacuation without sacrificing high-temperature traction. The contact patch is optimised to provide reliable braking distance and even wear across aggressive riding styles. Reinforcement in the sidewall aids stability under hard braking and rapid directional changes.

For the rider this tyre offers immediate feedback, improved steering response and a secure feeling when pushing harder on road or circuit. You gain predictable mileage and even wear along with reinforced sidewall support that helps maintain performance under load.
