The Regina 525 HPE drive chain is a high-performance motorcycle chain designed for riders seeking efficient power transfer, reduced maintenance, and dependable service life. This chain includes 124 links and uses Regina’s advanced Tetrahedral Amorphous Carbon (ta-C) coating on the bushing and roller surfaces. The coating combines high hardness with a low coefficient of friction to help reduce drivetrain losses while supporting consistent performance.
Designed for use with steel sprockets only, the Regina 525 HPE chain helps eliminate the need for periodic relubrication under normal operating conditions. It is engineered to provide at least the same mileage typically achieved with a conventional chain that is regularly lubricated every 310 miles. By reducing lubricant requirements, it also helps minimize lubricant spatter during operation and can lower ongoing spending on chain lubricant, fuel consumption, and motorcycle cleaning products.
The Regina 525 HPE is suitable as a replacement drive chain for compatible motorcycles using a 525-size chain and matching steel sprockets. Always verify the motorcycle manufacturer’s fitment specifications, chain length requirements, sprocket compatibility, and installation procedures before purchase or installation. Manufacturer part number 137HPE/1009 and vendor part number 137HPE/1009 identify this Regina chain configuration.
