The Regina 525 HPE Drive Chain is a high-performance motorcycle chain designed for riders seeking efficient power transfer and reduced maintenance. This 116-link chain features Regina’s advanced tetrahedral amorphous carbon (ta-C) coating, a diamond-like carbon (DLC) treatment applied to the bushing and roller surfaces. The coating combines high hardness with a low coefficient of friction to support smooth, efficient chain operation.
The 525 HPE chain is engineered to eliminate the need for periodic relubrication while delivering at least the mileage typically achieved with a conventional chain maintained with lubricant every 310 miles. By reducing friction and energy dissipation in the chain drive, it helps transmit more power to the rear wheel and may reduce spending on chain lubricant, fuel consumption, and motorcycle cleaning products. The dry-running design also eliminates lubricant spatter during operation, helping minimize maintenance and environmental impact.
For proper fitment and performance, this Regina chain is intended for compatible motorcycle applications using 525-size chain systems and steel sprockets only. Verify the motorcycle manufacturer’s chain size, required link count, and sprocket compatibility before installation. Manufactured by Regina and identified by manufacturer and vendor part number 137HPE/1005, this chain is suitable for riders who want durable construction, low-friction performance, and simplified chain care.
