Bridgestone Battlecross X40 Motocross technology for hard floors For hard floors MX technology at the highest level Stable driving feel when braking Safe adhesion in curves Rear tire with Castle Block technology Used technologies from FIM Moto-Cross-WM and the American AMA The profile of the front tire has an asymmetrical profile, which gives a stable driving feel during braking and safe grip in corners. Own tests show a significant improvement of the grip level of both profiles compared to the successful predecessors M403 and M603. For the rear wheel, the Bridgestone engineers developed the new Castle Block technology. The double edge, which reminds optically of castle towers ("Castles"), gets the tire better traction, which has a positive effect on the lap times. For the first time, so-called "cooling fins" are used in the motocross area - a technology that gives the tire greater consistency through active cooling of the sidewalls.
