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. 

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.
