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 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 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 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! 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!

Included in this kit

• Heavy-duty Kokusan brand recall-type OEM flywheel
• Triple-tested heavy-duty stator
• Mosfet voltage regulator rectifier
• Crankcase cover gasket
• Flywheel puller

Note:

• There are 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
