Bridgestone 22146 Battlax Hypersport S21 Front Motorcycle Tire 130/70ZR16 61W

The Bridgestone Battlax Hypersport S21 is a premium radial motorcycle tire engineered to deliver elite sport performance on the street and track. Sized 130/70ZR16 61W, this is a front tire position fitment designed for supersport and sport motorcycles. Building on the proven wet-weather capability of the Battlax S20 EVO, the S21 introduces advanced compound and construction technologies that push dry grip, stability, and tread life to a new level.

Key Features:

• 3-Layer Compound (3LC) Front Construction — Dual-compound front tire design puts the right compound in the right zone of the tread for optimized grip across the contact patch
• Enhanced Micro-Contact-Patch (EMC) Shoulder Compound — Increases grip potential and improves thermal stability at the shoulders for consistent cornering performance
• ULTIMAT EYE™ Technology — Bridgestone's proprietary contact patch visualization system used in development to measure tire behavior at varying speeds, lean angles, and conditions
• 3D Groove End Tread Pattern — Engineered groove layout with near-slick shoulders optimizes tread rigidity, contact patch performance, and wet drainage simultaneously
• Up to 36% More Mileage — Significant improvement in tread life compared to the predecessor S20, without sacrificing handling performance
• Smaller Crown Profile — Revised front profile generates a longer contact patch for improved feel and stability at lower lean angles
• High-Stiffness Bead Fillers — Provide optimum damping and straight-line stability
• Tubeless (TL) Construction — Blackwall sidewall finish
