The Holeshot SX has been carefully designed and painstakingly developed to dominate on hard-packed motocross tracks. Key to this process was the extensive input of several National-caliber race teams and riders, who specifically requested a tire that could excel on this type of MX course. The drier, slicker and faster the track surface - a very common condition in todays racing environment - the greater an advantage the Holeshot SX rider will enjoy. Reinforced carcass that minimizes stretching while maintaining a flat profile, thus providing consistent feel and performance without a sacrifice in ride comfort. New "RR" tread compound has been formulated, and after extensive testing has proven to provide unmatched hard pack performance as well as surprisingly long tire life (getting more motos out of a set of tires was a primary goal). SX tread pattern uses more tightly spaced knobs to increase the tire contact patch, while the redesigned knobs themselves have been laterally sipped (thinly cut) to yield twice the number of biting edges than any Holeshot tire thats come before. Shoulder knobs utilize a new tapered shape that offers greater control during corner transitions. Tire ply: 2.
