Kit Stator + Mosfet Voltage Regulator for Honda TRX 250 X / EX 2006-2024 | # 31120-HN6-A31 31600-HM8-B00
Kit Stator + Mosfet Voltage Regulator for Honda TRX 250 X / EX 2006-2024 | # 31120-HN6-A31 31600-HM8-B00
Battery condition is important. No stator, nor regulator can make up for a bad or weak battery. If in doubt charge your battery and have it load tested, or simply replace it. ALWAYS START WITH A FULLY CHARGED BATTERY !

Brand new Mosfet Voltage Regulator Rectifier
STOP BURNING YOUR REGULATOR RECTIFIER !
It is time to update or replace your voltage regulator with the advanced MOSFET type.
It runs cooler than all OEM diode style regulators. In addition, this rectifier has overheat protection, rather than burn up it will simply turn off for a while and cool off.
Key features
IMPROVED & HEAVY DUTY: OEM and most SCR type voltage regulator are known to fail more than often for these vehicles. Our RMS Labs took a best selling voltage regulator and made it tougher by using highly reliable components to regulate the voltage. The result : More than 83% less failures than a standard OEM-type voltage regulator.
RMSTATOR RENOWNED MOSFET COMPONENTS: Significantly decreases internal operating temperature with highly efficient MOSFET transistor regulation circuit. This technology runs much cooler than the OEM silicon rectifier regulation circuit and requires much less power to operate.
AUTOMOTIVE GRADE HEAVY-DUTY CONNECTORS: Increase contact surface for distributed voltage charge on pins & less heat generated at connectors levels
- The quality exceeds the OEM equipment
- Higher grade of electric components
Why use Mosfet Enhanced technology?


Runs cooler
Runs much cooler than the traditional Shunt voltage regulator rectifier.

Saves gas
Less load on the stator, less work, less fuel is used and you save.

Regulated energy
The power charging your battery is steadier and smooth.

Extended battery life
Extends the battery’s life and cold cranking capacity.

More engine power
Removes stator load resulting in more engine power.

Optimized power
Optimize power delivery by switching the stator coils on or off.

With
design
This product is an advanced design that lowers operating temperatures for extended longevity and better performance than the OEM part.

Installation
Installation
Before installing your new Mosfet Voltage Regulator Rectifier :
- Check the AC output of the stator
- Replace any burned or corroded connectors on stator and regulator rectifier
- Check and repair any melted wiring
- Use hi-temp dielectric grease on all connectors
Warning:
Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
