An intermediate-to-hard terrain motocross tire developed to deliver long-lasting performance across the conditions riders encounter most. FEATURES Optimized for intermediate terrain with expanded performance into hard packed conditions, giving riders confidence as tracks dry and develop. Revised tread pattern increases land ratio for improved hard pack performance while maintaining grip in intermediate conditions. Multiple Block Distribution (MBD) enhances ground contact feel and predictability under load for improved rider feedback and control. Progressive Cornering Block Technology (PCBT Advanced) improves cornering grip, slide control, and traction on hard packed terrain. Continuous center groove on the front tire improves braking grip and delivers stable, predictable handling across changing track conditions. High-Resilience Rubber Compound (*select rear sizes) enhances traction, durability, and performance longevity under high loads. Approximately 5% taller rear block height improves traction and durability in demanding conditions. Balanced performance across race conditions including traction, cornering grip, durability, and predictability from start to finish. PCBT Advanced Improves grip while cornering with enhanced feel and absorption. HIGH-RESILIENCE RUBBER COMPOUND Improves the rubber&';s strength, which increases traction and performance through less knob flex.
