The Bridgestone Battlecross X40R rear tire is built for riders who need dependable traction on hard terrain, from baked clay tracks to rugged, rock-strewn trails. Its Castle Block design creates extra biting edges that dig in under acceleration and braking, giving you confident drive and precise control when the surface offers little forgiveness. Advanced Cooling Fins on the sidewall help manage heat, allowing the tire to stay consistent during long motos or demanding trail sessions.
Inside, the X40R uses Bridgestone’s MS-Belt and a seamless one-piece construction that keeps the tire light, responsive and stable at speed. The balanced compound gives you predictable handling through the center while the shoulders maintain grip when the bike leans into ruts or hardpack corners. For riders who push through harsh terrain and expect their rear tire to keep up, the X40R delivers the bite, stability and consistency you need.
