MOSFET Charging Upgrade
Fits Honda VFR800, CBR600F4i & CBR900/929RR
Solve persistent charging problems on your Honda sportbike with this **MOSFET Regulator Rectifier & Loom Bypass Kit**. Honda VFR and CBR models from the early 2000s are notorious for melting stator connectors and wiring harness failures due to overheating stock regulators.
This kit includes a modern, cool-running **MOSFET Regulator** capable of handling 50 Amps, paired with a **Loom Bypass Harness**. This harness connects the regulator directly to the battery and stator, completely bypassing the potentially corroded or undersized factory wiring that causes voltage drops and charging failures.
Key Features
- ✔ MOSFET Tech: Runs significantly cooler.
- ✔ Loom Bypass: Replaces faulty stock wiring.
- ✔ High Capacity: 50A Peak / 500W output.
- ✔ Plug & Play: connectors for stator/battery.

Frequently Asked Questions
Why do I need a loom bypass?
The factory wiring on VFR800s and CBRs is prone to resistance and melting at the connectors. This kit bypasses that problematic wiring, sending charge directly to the battery for better reliability.
Is this better than the stock regulator?
Yes, this is a MOSFET regulator which operates much cooler than the old shunt-style OEM units, significantly extending the life of your charging system.
Is it hard to install?
Installation is straightforward. You mount the regulator, connect the new harness to your stator output wires, and connect the other end directly to your battery terminals.
Note: Please check your stator condition before installing. A burnt stator can damage a new regulator.
