**Shineray Electric Dirt bike - Rear Drive Sprocket**

**Product Description:**
Precisely convert motor power into wheel torque with this heavy-duty Rear Drive Sprocket, engineered for the Shineray electric dirt bike. This critical transmission component is built to reliably handle the high instantaneous torque of the electric motor, ensuring efficient power transfer, smooth acceleration, and long-lasting performance on demanding trails. Manufactured from high-strength alloy steel with a hardened finish, it offers superior wear resistance for extended service life.

**Key Features & Specifications:**

*   **High-Torque Design:** Specifically engineered to withstand the **33Nm peak motor torque** and the amplified **350Nm rear wheel torque**, providing a durable and reliable link in the drivetrain.
*   **Premium Material & Finish:** Constructed from high-grade alloy steel and features a hardened surface treatment for exceptional resistance to wear, elongation, and chain abrasion.
*   **Precision Fit:** Designed as a direct OEM replacement to ensure perfect alignment with the rear wheel hub, correct chain line, and compatibility with the standard drive chain.
*   **Optimized Performance:** The precisely machined tooth profile ensures smooth and quiet engagement with the chain, minimizing power loss and contributing to the bike's overall efficiency and range.
*   **Easy Installation:** Includes all necessary mounting hardware (where applicable) for straightforward replacement during maintenance or gear ratio customization.

**Detailed Specification:**

*   **Compatibility:** Shineray Electric Dirt bike (Please verify specific model)
*   **Position:** Rear Wheel / Final Drive
*   **Material:** High-Strength Alloy Steel, Hardened
*   **Tooth Count:** [e.g., 45T, 48T, etc. - **Please specify based on actual product**]
*   **Mounting Pattern:** Matches OEM hub bolt circle
*   **Application:** Designed for standard 420 or 428 chain size (as per OEM spec)

**Ideal For:**

*   Replacing a worn, hooked, or damaged stock sprocket as part of routine drive train maintenance.
*   Upgrading to a premium sprocket for improved durability and performance.
*   Changing the final drive ratio (by selecting a different tooth count) to prioritize acceleration or top speed, in conjunction with the front counter sprocket.

**Note:**
For optimal performance and chain life, it is highly recommended to replace the rear sprocket, front counter sprocket, and drive chain as a complete set. Always verify the exact tooth count and chain pitch compatibility with your specific Shineray model. Ensure proper torque specification when mounting the sprocket to the hub. Regular inspection for wear is advised.
