Key Features

• Extreme Low-End Torque: The 12-tooth design provides a high mechanical advantage, making it much easier to pull through mud, climb steep inclines, and achieve quick acceleration from a standstill.
• Precision Processing Technology: Manufactured with advanced machining techniques to ensure a perfect tooth profile. This improves transmission efficiency and results in a significantly more silent drive system with less vibration. 
• Hot-Treated Steel Construction: The steel is subjected to a specialized heat-treatment process to increase hardness and wear resistance, ensuring the sprocket remains durable under extreme loads and high-heat operation.
• Complete Installation Kit: This sprocket comes with all necessary accessories, including the retainer plate and bolts, allowing for a direct installation with no additional tools required.
• Enhanced Drive Stability: Designed specifically for the 428 chain, the wider tooth profile provides a more stable interface, reducing the risk of chain derailment or "jumping" during aggressive riding.
