- Plug-and-play, direct fit, easy installation
- All products shipped are tested
All item pictures are accurate; if in doubt do not hesitate to compare our item to your original part.
Brand new aftermarket stator
- Highest-grade lamination materials
- Highest-grade copper windings, resistant to 200 degrees Celsius.
- Connector included
- Rubber grommet included
We have even included the opposite connector (main harness side), as we know these are often melted / corroded / defective and a major cause of repetitive electrical issues.
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.
- Plug-and-play, direct fit, easy installation
- The quality exceeds the OEM equipment
- Improved heat sink and charging capabilities
- 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.

Note:
- Battery condition is extremely important. No stator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.
- When using our Aprilia MOSFET regulator on Tuono V4 applications, the larger regulator housing is a very tight fit. It may require slight cutting, grinding, or modification to the plastic mounting area to clear the larger housing and wiring harness.
