Recall-Type Stator Flywheel Rotor For Aprilia 2009-2017 RSV4 & 2011-2017 Tuono V4 Repl.# 2D000049 897479

Introducing our newest heavy-duty recall-type charging system upgrade kit for Aprilia 2009-2017 RSV4 & 2011-2017 Tuono V4.

Anyone who rides or repairs Aprilia’s motorcycles is probably familiar with the stator, flywheel, and sometimes voltage regulator issues common to these models. Most of these bikes will have had at least one stator fail in its lifetime so far. The main problem was extremely strong magnets were used on the original flywheels, creating a very high power stator output, which generated excessive heat. This usually resulted in burned up, or shorted stator windings, and often in a failed voltage regulator.

The solution was a new flywheel from Kokusan with lower strength magnets, dropping the stator output and heat generation. This results in a charging system output perfectly matched for the bike’s electronic needs, and long term reliability of the stator and voltage regulator.

To prevent or correct the flywheel problems, our engineers at RMS Labs have come up with a complete reliable heavy-duty charging system replacement kit for your Aprilia. Upgrade today if you haven’t already!

Included in this kit

  • Heavy-duty Kokusan brand recall-type OEM flywheel
  • Triple-tested heavy-duty stator

With this kit, you will be able to upgrade your current failure-prone charging system with a heavy-duty version using the latest technologies

Features

Kokusan upgrade/recall type flywheel

Lower-strength magnets for correct stator output, low heat generation, and long-term reliability.

Built to OEM size

Fits precisely in your ride: install it and forget it.

Improved epoxy

Uses high temperature epoxy that is stronger than OEM, eliminating the possibility of magnet detachment

High grade steel capping

Prevents harsh additives in motor oil from degrading the epoxy attaching the magnets. Though extremely unlikely, if a magnet did ever come loose, it would remain in the sleeve preventing contact with the stator.

Precise balancing

Eliminates crankshaft vibrations for longer engine longevity.

Shop with confidence

All products are tested.

Don't waste time with temporary solutions, and start fixing your ride like a pro!


Please note: There is two possible kits for RSV4 engine. This kit ONLY fits RSV4 engine numbers HIGHER than 3413 with Kokusan flywheels. Please compare our flywheel to your original.

If your RSV4 engine number is LOWER than 3413, your motor uses the Mitsubishi flywheel, and will need Stator Assembly 857201. RMSTATOR DOES NOT currently have these parts available.

Installation instructions

Stator :

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 may use a different wire color code than your original.
All of 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 no less than 0.010''.


Voltage regulator :

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.

Flywheel :

Before attempting to start your Aprilia adjusting the air gap is necessary. Rotate the flywheel so the raised node is lined up with the pick up/pulsar coil and adjust as close as possible but no less than 0.010''.
