Brigestone's Battlax Hypersport S21 delivers Battlax DNA at an entry level price. S21 was the first Bridgestone tire designed using Bridgestone's UltimateEye Technology and started the performance progression which continues today.

Pulse Groove
Improved water channeling and drainage resulting in enhanced grip and reduced tire slip ratio in wet conditions. Pulse Groove Technology works by combining pulse-shaped grooves with small center deflectors to equalize waterflow, which optimizes waterflow speed compared to a straight groove. Watch our video about Pulse Groove.

MS•BELT
MSB construction means that a continuous single strand is wrapped around the circumference of the tire. This one-piece construction eliminates overlapping of belts, seams, and joints. An MSB tire is lighter than conventional multi-cross belt construction, it also has more stability since it minimizes heat generation inside the tire and gives high shock absorption.

ULTIMATEYE
Visualization of the tire contact patch behavior with measurement and simulation technology. Supplies less slip area for good traction while riding and improves wear life.

Cap&Base
The underlying layer controls tread stiffness, reinforcement and assists with bump absorption.

3LC (Dual Compound)
Provides grip performance demanded in all riding modes. The center compound offers linear handling. The shoulder compound secures high grip and solid contact feel.

HTSPC
Bridgestone was the very first motorcycle tire manufacturer to utilize 1X5 filament rubber insulated steel (MSB) in the manufacture of its motorcycle radial tires. This makes the tire more flexible, provides more stability without a reduction in shock absorption, and minimizes the generation of heat throughout the tire.

RC Polymer
RC Polymer technology optimizes the distribution of silica within the rubber compound and improves tread flexibility allowing greater contact with the road surface in both hot and cold conditions. The reduction in molecular friction also improves rolling resistance, therefore increasing fuel economy.

3LC+CAP&BASE
The CAP&BASE construction divides the shoulder of the compound of the tire into upper and lower sections. By using a high grip compound for the upper section of the shoulder, and a high stability abrasion resistant compound for the lower and central sections, this provides the desired combination of both performance and mileage.
