Bridgestone Battlax Hypersport S21 Rear Motorcycle Tire 180/55R17 73W

The Bridgestone Battlax Hypersport S21 Rear Motorcycle Tire 180/55R17 73W is a radial sport tire built for riders who push hard on the street and want consistent performance as the tire heats up. Bridgestone uses their Enhanced Micro-contact-patch Compound in the shoulder area to keep grip stable across a range of operating temperatures. Three-dimensional cross grooves in the tread work to maintain road contact and manage tread block rigidity. The result, according to Bridgestone, is a meaningful gain in dry grip and tread life that does not come at the expense of wet performance.

This tire is a 180/55R17 rear fitment, meaning the section width is 180 mm, the sidewall height is 55 percent of that width, and the tire mounts on a 17-inch rim. The rim diameter must match your wheel exactly, and the full size code should match the size printed on the sidewall of the tire you are replacing. It carries a load index of 73 and a W speed rating, which covers speeds up to 168 mph, and both values must meet or exceed what your machine's specification requires. The S21 is built for hypersport street riding where strong dry grip is the priority.
