For riders and mechanics, engine overheating is a common and frustrating issue, especially in summer traffic or during long rides. It compromises performance, accelerates engine wear, and leads to costly repairs. Often, the root cause is an underperforming cooling fan.

The Cooling Bottleneck: Limitations of Conventional Fan Motors
Stock or standard replacement fans on many motorcycles can lose efficiency over time. The traditional “iron-core” motor design has inherent drawbacks: high rotational inertia (slow response), higher energy consumption, and increased noise. When you need maximum cooling instantly, they may fail to deliver.

The High-Efficiency Solution: Haershi (HES) Coreless Motor Technology
We address this core issue by specializing in the design and manufacture of advanced “Coreless Rotor” fan motors. This technology delivers three key advantages:

1. Rapid Response & Superior Cooling: By eliminating the heavy iron core, the rotor becomes significantly lighter. This allows the fan to start up and reach peak speed much faster, generating strong airflow immediately during idle or stop-and-go traffic to pull heat away effectively.

2. Lower Power Consumption & Smooth Operation: The optimized electromagnetic design and lightweight rotor reduce the motor's power draw, easing the load on your battery. Operation is also smoother and quieter.

3. Robust Construction & Enhanced Durability: With a more compact, integrated design and high-quality materials, our motors offer excellent resistance to vibration and wear, ensuring long-term reliability in harsh under-hood environments.

Our Commitment: From Precise Fitment to Rapid Support
At HES, we provide more than parts—we deliver reliable cooling solutions.

• Precise OEM-Level Fit: Our fans are engineered to match original specifications, ensuring a perfect fit for your motorcycle's radiator for straightforward installation.

• Strong ODM Customization Capability: Whether you need a solution for a specific model, a custom build, or a special application (e.g., police fleets, off-road teams), our engineering team can collaborate on a tailored design.

• 72-Hour Fast Dispatch: We value your time. Standard models can be prepared for shipping within 72 hours after order confirmation.

A cool engine is a reliable engine. Choosing a high-efficiency cooling fan is fundamental to protecting your motorcycle's heart.
