Before installing your new Stator

  • 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

Our stator might have a different wire color code than your original part.
All the wires are installed in the correct order; please do not change any of the wiring configurations.
This stator is designed as a direct plug-in replacement and should be used as such.
When bolting stator in, always use locking compound.
If our stator includes a pickup coil, always make sure the air gap is correct upon installation; we suggest as close as possible but no less than 0.010".

Before installing your new 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

Regulator installs in the OEM mounting location. It must be installed with connectors facing up. It is a tight fit, but will slid behind the radiator coolant tube and thermostat housing. This is the only way for the vehicle adapter harness to be installed correctly.

Brand new aftermarket Stator + Red Machined Aluminum Mosfet Regulator Kit

All item pictures are accurate, if in doubt, do not hesitate and compare our item to your original part.

The 2004-2009 Aprilia RSV and Tuono models are excellent motorcycles, but all suffered from a very unreliable charging system. The issue was an extremely strong magnetic flywheel that caused excess heat in the stator windings and common repeat failures. A replacement stator of the original design was simply not a reliable solution. The high output from the stator also caused regular voltage regulator failures, making for a very poor charging system.

To solve this problem, RMSTATOR has engineered a permanent solution kit to address all parts of the charging system. A thinner stator core is used that generates and retains less heat in use, and promotes cooling due to increased oil coverage from the extra space inside the flywheel. Paired with a CNC billet aluminum machined series type voltage regulator, the charging system is now bulletproof. For a complete and easy installation, we include shorter stator mounting bolts, a plug & play adapter harness for the new voltage regulator, and a stator cover gasket.


  • Highest grade of lamination materials
  • Highest grade of copper winding, resistant to 200 degrees Celsius
  • Tow pick up pulsar coil included
  • Connectors included
  • Rubber grommet included

SERIES regulators run much cooler than the Shunt and MOSFET voltage regulator rectifier and way much cooler than OEM parts.

Moreover, the regulator has our new machined billet aluminum casing which dissipate heat 33% better than standard molded casing.

Power only flows through the electrical components when the battery is charging.

Allows the stator to have lower current flowing when not used, extending its lifetime.


RMSTATOR’s new SERIES voltage regulator brings better reliability and charging system performance. A SERIES regulator is a significant upgrade over typical shunt type voltage regulators.

A shunt regulator controls battery voltage by grounding the stator coils to dissipate current as heat, rather than sending it on to the battery. SERIES regulators control battery voltage by intermittently disconnecting stator coils from the regulator electronics, limiting current flow through the unit and on to the battery completely.

This results in lower regulator and stator temperatures, more accurate voltage regulation, and increased reliability of your charging system components.


We include the opposite connector (main harness side) as we know these are often melted / corroded / defective. Defective connectors are a major cause for repetitive electrical issues.
