- Precision construction for performance: high-strength 5/8 inch bore 11-tooth clutch set for go-karts and mini bikes. Designed for precise tuning to improve running efficiency and driving feel. - High-strength design for durability: 5/8 inch bore with 11-tooth design to withstand greater forces and stay stable at high speeds. Suitable for single-wheel drive karts with tyre height up to 15 inches. - Safe, reliable and wear-resistant: go kart coupling with 5/8 inch bore emphasizes safety and reliability. High wear resistance and fast heat dissipation help protect the vehicle and rider from adverse conditions. - Advanced material for long-lasting performance: 11-tooth go-kart coupling made from high-quality, wear-resistant materials to ensure durable, long-lasting operation. Use scenarios: - Upgrading a stock go-kart drive system for improved acceleration, reliability and control in youth racing or recreational rides (single-wheel drive, up to 15 inch tyres). - Replacing worn or damaged clutch components on DIY mini bike builds to maintain consistent performance and safety. - Retrofitting or maintaining racing karts that operate at higher loads, where stable engagement and durable wear resistance are required.
