All new for 2006! The next-generation high-performance motocross knobby. The most technologically advanced race tire ever! Specifically designed and developed to dominate on the hard-packed MX tracks so common in ATV racing today. The drier and slicker the track surface, the greater advantage the Holeshot SX rider will enjoy. Rear Holeshot SX utilizes a specially reinforced carcass that minimizes stretching while maintaining a flat profile, providing consistent feel and performance without a sacrifice in ride comfort. Front Holeshot SX also incorporates a tighter knob pattern and sipped knobs for increased contact area, improved steering response and better braking control in hard-pack conditions. Front: 20x6-10 (2-ply); Rear: 18x10-8 (2-ply)
