The Battlax V03 tire is a track-only racing slick tire and the pinnacle of Bridgestone racing technology, building on the reputation of the previous generation V02. The V03 tire incorporates new technologies developed through real-world racing conditions in some of the world’s top championship race series. With new compounds and an increased contact patch, the Battlax V03 is able to deliver improved dry grip** and uniform pressure distribution for stability and speed through corners. Plus, the V03 is engineered to deliver peak performance consistently throughout multiple laps and heat cycles to help give you more chances to post your fastest lap. **Comparison based on internal testing of the Bridgestone Battlax V03F Soft/V03R Sprint vs. the Bridgestone Battlax V02F NS-Soft/V02R NS-Soft after one lap session. Results may vary depending on proper tire and vehicle maintenance, surface conditions and riding habits. Advanced Sprint Compound helps deliver commanding grip for faster lap times. Increased Contact Patch supports enhanced grip and a stable, confident feel. Advanced Construction Technology helps maintain consistent, high performance across multiple laps and heat cycles. Track use only, tire warmers recommended. NOT for use on public roads. Mono Spiral 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. High Tensile Super Penetrated Cord 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. 3LC (Dual Compound) Used in "Extra Soft" Models: Provides grip performance demanded in all riding modes. The center "Soft" compound offers linear handling, while the "Extra Soft" shoulder compound secures high grip and solid contact feel.
