Description
Bridgestone built the Battlax Hypersport S21R rear around a five-compound layout specifically to handle the demands of hard acceleration and lean-angle grip at the same time, and this 190/55ZR17 size fits a wide range of sport bikes.
The rear tire does the heavy lifting under acceleration, and it is the one most riders wear out first if they spend any real time on the throttle. Bridgestone built this Hypersport rear to resist squaring off in the center while still giving predictable grip out at full lean, so the bike keeps its composure whether you are rolling on the power mid-corner or driving hard off the final apex before a straight.
Key specs and features:
- Rear tire size 190/55ZR17, radial construction, rated 75W
- Part of the Battlax Hypersport S21 line: built around Bridgestone’s EMC micro-contact-patch technology and 3D cross grooves for rigidity and road contact
- Tread built around a five-compound (5LC) layout with a revised profile aimed at both stability under acceleration and durability
- Tubeless radial casing designed to hold its shape under hard acceleration out of corners
- Wide contact patch intended to manage power delivery on modern sport bikes without excess squirm
- Suited to street riding, aggressive backroad pace, and occasional track day duty
Run this 75W rear with a matching S21 front for the intended handling balance, and note the triple-compound layout is most effective once the tire is properly scrubbed in during the first several miles of riding.
