Premium Quality Replacement for Honda CRF EFI Models
Upgrade your Honda's charging system with this heavy-duty aftermarket voltage regulator rectifier. Specifically engineered for the newer fuel-injected (EFI) Honda CRF 110 and 125 models, this unit is designed to outperform the stock component. Electrical failures on these bikes are often caused by corroded or melted connectors on the main harness side; to ensure a permanent fix, this kit includes the opposite connector (main harness side) to replace damaged wiring during installation.

Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part from 4Drive, manufactured to meet or exceed original equipment (OE) standards for fitment and electrical performance.
How do I know if it is compatible?
We recommend checking the SKU/MPN and Cross Reference list provided above. If your original part number is 31600-KZP-671, this is the correct unit for your machine.
Why is an extra connector included?
The main wiring harness connector on the CRF 110/125 often melts or corrodes when the regulator fails. We include the matching female/male connector kit so you can replace the damaged harness side, preventing future failures.
Note: Always ensure your battery is fully charged and load-tested before installing a new regulator. Please verify your original part number before purchasing.
