Available in two rubber compounds to ensure a wide range of use depending on the temperature and difficulty of the track, the Bridgestone Battlax Racing R11 is equipped with a new progressive monospiral belt that offers performance in terms of pressure uniformity on the contact surface and improves the spacing of the HTSPC system of wound steel monofilaments. By perfecting the tread stiffness, the contact surface of the front tire at the entrance of the turn is improved for maximum lean angle and a reduction of contact surface during braking.
