Recall-Type Kokusan Stator For Aprilia 2011-2020 RSV4 & 2011-2020 Tuono V4 Repl.# 2D000049 897479
Introducing our newest heavy-duty recall-type charging system upgrade stator for Aprilia 2011-2020 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!
- Direct replacement to your original unit
- Plug-and-play, direct fit, easy installation
- Highest grade of lamination materials
- Highest grade of copper winding, resistant to 200 degrees Celsius
- Connectors included
- Rubber grommet included
- All products shipped are tested
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.
All item pictures are accurate; if in doubt, do not hesitate to compare our item to your original part.
Don't waste time with temporary solutions, and start fixing your ride like a pro!

Installation
Installation
Before installing your new improved kokusan 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".
Due to the shallow taper of the Aprilia crankshaft, it is critical to use the OEM flywheel lockup tool (Aprilia Part Number 020914Y) to secure the flywheel from turning while you loosen and tighten the flywheel bolt. Do NOT use an impact gun, especially to install the flywheel bolt, as the massive torque can force the flywheel too far onto the crankshaft and rub on the timing chain guide bolt behind it. The flywheel bolt MUST be tightened with a torque wrench to the OEM spec of 88 ft/lbs (120 N/m) to prevent any issues.
Warning:
Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
