Bridgestone Tire Battlax Rs12 Rear 180/55zr17 73w Radial Tl

The Bridgestone Battlax Racing Street RS12 tire is the most aggressive Hypersport tire in the Bridgestone lineup. Whether you are carving canyons or hitting your favorite track’s apex, the RS12 is engineered for riders who want incredible track-day performance without committing to slicks. The RS12 tire is engineered for impressive dry grip, confident handling, with visually striking sidewalls and tread. This delivers a tire that was designed for fast and consistent lap times while accelerating your enjoyment on both the circuit and the street.

• Maximum Dry Grip: Bridgestone race tire compound technology helps deliver amazing grip and durability for both track and street riding.
• The new steel HE-MSB* construction in the front tires is engineered for stabilizing and equalizing pressure under extreme braking loads, while the wide shoulder of advanced race compound on the rear helps drive out of corners.
• Consistent Lap Time: Race tire compounds developed in endurance racing help deliver fast times, lap after lap.
• Racing-Inspired Appearance: A slick, redesigned shoulder provides a true racing aesthetic and a contact patch increase of 9% on the front tire and a 4% on the rear tire compared to the preceding RS11 tire. Form follows function.
• *High Elongation Mono Spiral Belt (HE-MSB)
