Moto-Electrical recently launched a high quality and value for money upgrade kit for the Aprilia RSV4 (2009-2017) / Tuono (2011-2017).

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.

RMStator realised there was an ongoing issue and discovered that a 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, the engineers over at RMStator came up with a complete reliable heavy-duty charging system replacement kit for your Aprilia.

The kit Moto-Electrical have launched includes a brand new MOSFET voltage regulator since it is often damaged when stators fails, a heavy-duty Kokusan OEM flywheel and a triple-tested heavy-duty stator. If you are unfamiliar with MOSFET technology, this is where the internal operating temperatures are significantly lowered due to the highly efficient MOSFET transistor regulation circuit.

To find the kit on Moto-Electrical, use part number RMS900-103810.

With this kit you will be able to upgrade your current failure-prone charging system with a heavy-duty version using the latest technologies.

So, don’t waste your time with temporary solutions, and start fixing your ride like a pro!
