Recall-Type Stator Flywheel Rotor Gasket & MOSFET Voltage Regulator For Aprilia 2011-2017 RSV4 & 2011-2017 Tuono V4 Repl.# 2D000049 897479 B043488

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

Anyone who rides or repairs Aprilia’s motorcycles is probably familiar with the flywheel problems common to these models. Most of these bikes will have had at least one flywheel failure in their lifetime so far. Low quality epoxy was used on OEM flywheels to secure the magnets to the rotor body. Over time and many heat cycles, the epoxy fails allowing the magnets to come loose and contact the stator, potentially causing catastrophic damage.

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. The kit includes a brand new MOSFET voltage regulator since it is often damaged when stators fails.

Included in this kit

  • Heavy-duty Kokusan brand recall-type OEM flywheel
  • Triple-tested heavy-duty stator
  • Heavy-duty voltage regulator with RMSTATOR’s renowned MOSFET regulation technology
  • Stator crank case cover gasket

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

Built to OEM size

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

RMSTATOR renowned MOSFET voltage regulation design

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.

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

One year warranty. All products are tested.

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


Please note: This version of the stator and flywheel are in use for RSV4 engine numbers higher than 3413 only. All Tuono V4s seem to use this Kokusan version. Double-check the flywheel with your original before buying this kit.

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''.
