Introducing our newest heavy-duty recall-type charging system upgrade kit for Aprilia 2009-2020 RSV4 & 2011-2020 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 their 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 winding, 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 the 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 completely 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
• Stator crankcase cover gasket
• Flywheel puller

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!

• Exterior diameter: 105 mm
• Thickness: 13.8 mm
• Length of wires stator to grommet: 125 mm
• Length of wires grommet to plug: 320 mm
• Other specifications:
• Number of wires: 3
• Number of plugs: 1
• Number of pins: 3
• Alternator: Between each Yellow = 0.3 ohms +-20%
• Flywheel Dimensions:

Please note: There are two possible kits for the 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. Refer to kit RMS900104929.

Brand new RMSTATOR Red Machined Aluminum Mosfet Regulator

Our new RMSTATOR machined aluminium Mosfet voltage regulator is a great upgrade for heat dissipation in any powersports charging system. After 10 minutes of use, our billet aluminium heatsink runs cooler by 33% than standard cast regulator housings. Our new RMSTATOR red regulator, equipped with the renowned Mosfet regulation technology, is an added value to any three-phase permanent magnet charging system.

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.

• The quality exceeds the OEM equipment
• Improved heat sink and charging capabilities
• Higher grade of electric components

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.

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