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!

Improved Magneto Flywheel Rotor

RMSTATOR is offering a new improved replacement flywheel for your Suzuki and Arctic Cat. This flywheel can be used as a direct replacement to the OEM.

All item pictures are accurate; if in doubt, do not hesitate to compare our item to your original part

What is improved about the RM11502 flywheel?

2002-2007 Suzuki Eiger 400 and 2003-2008 Arctic Cat 400 ATVs are plagued with problems on the original flywheels. The additives in the motor oil were dissolving the epoxy that holds the magnets in the flywheel, causing them to detach and scatter throughout the engine.

• EXPOSED EPOXY
• DETACHED MAGNET

The bad news is that by the time the problem occurred, no manufacturer would provide warranty repairs.

The good news is that RMSTATOR has manufactured a redesigned flywheel where the magnets are sealed in the flywheel, which reinforces the epoxy and prevents them from detaching. This new flywheel configuration corrects the problem permanently.

Dealership estimates to repair this failure are over $500 in parts alone. RMSTATOR offers you a high-quality replacement part that corrects the problem for half the price. The RM11502 flywheel is not only a cost-effective way to replace your failed Suzuki or Arctic Cat flywheel, but a great investment when replaced before the failure occurs.

Please Note:

Introducing our newest heavy-duty flywheel rotor for Kawasaki 400 & 500 cc Motorcycles.

Anyone who rides or repairs a Kawasaki 400 or 500cc Motorcycle is probably familiar with the flywheel problems common to these models. Most of these bikes will have at least one flywheel failure in their lifetime. 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.

For years, service shops & dealerships have offered low-cost repairs for Kawasaki flywheels. This sounds like a great idea at first, but there are some serious issues!

The common repair is using Marine Blue Epoxy to reattach the loose original magnets or to install new ones. Epoxy fixes do repair flywheels in short term if they are done correctly. However, this kind of repair can easily cause immediate problems and impact long term reliability of your ATV.

Why cheap repairs won't work?

Quick stronger epoxy fixes do repair flywheels in short term. It might however impair long term performance and reliability of your ride.

• Remaining OEM magnets: Original magnets remaining can still come loose at any time.
• Magnet alignment: The alignment of magnets around the flywheel is critical for proper stator operation. Even very fine misalignment will reduce stator efficiency significantly.
• Magnet spacing: Excessive epoxy or incorrect magnet spacing around the flywheel can easily affect the flywheel balance. This can cause stator contact or even crankshaft damage.
• Incorrect replacement magnets: The magnetic field strength of new magnets MUST match the originals. Stator failure can occur quickly with stronger magnets and stator output can be decreased significantly using weaker magnets.
• Wrong epoxy properties: Epoxy that is not rated to permanently handle high temperatures and oil immersion can quickly cause a serious failure.
• Oil contamination: Wrong epoxy for the application can also contaminate the crankcase oil, damaging the motor.

All these reasons make us strongly recommend that you replace your broken flywheel with our new heavy-duty flywheel.

Dimensions:

• Exterior Diameter: 129 mm
• Interior Diameter: 106 mm
• Interior Diameter Center Housing: 16 mm
• Exterior Diameter Center Housing: 25 mm
• Thickness (exterior): 42 mm

Note: Before attempting to start your Kawasaki adjusting the air gap is necessary. Rotate the flywheel so the raised node is lined up with the pick up/pulser coil and adjust as close as possible but no less than 0.010".

Flywheel assembly + new cover seal

• Magneto flywheel

RMSTATOR offers a new flywheel with magnets for your Suzuki or your Arctic Cat. The flywheel can be used as a replacement to your original part

What is improved in our RM11502 flywheel?

The stock flywheels of the Suzuki Eiger 400 2002-2007 and Arctic Cat 400 2003-2008 ATVs have recurring problems. Additives in the engine oil dissolve the epoxy used to hold the magnets in place, causing them to loosen and disperse in the engine.

• EPOXY EXPOSED
• MAGNET DETACHED

The problem encountered by owners of these ATVs is that no manufacturer wants to guarantee this part on such old vehicles. Faced with this situation, RMSTATOR has redesigned and improved the flywheel of these ATVs. The magnets are now sealed, which prevents them from coming loose. This new configuration fixes the problem for life. We offer a high quality part that permanently eliminates the problem for half the cost of the original part. The RM11502 flywheel is not an economical way to repair your ATV, but an investment when replaced before the original part breaks.

Machined Aluminum Mosfet Regulator

Our new red machined aluminum Mosfet voltage regulator is a great upgrade for heat dissipation in any power sports charging system. After 10 minutes of use, our billet aluminum heatsink runs cooler by 33% than standard cast regulator housings. Our new 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 to 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 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

• Incorrect replacement magnets: The magnetic field strength of new magnets MUST match the originals. Stator failure can occur quickly with stronger magnets and stator output can be decreased significantly using weaker magnets.
• Wrong epoxy properties: Epoxy that is not rated to permanently handle high temperatures and oil immersion can quickly cause a serious failure.
• Oil contamination: Wrong epoxy for the application can also contaminate the crankcase oil, damaging the motor.

Please Note:

1. All electrical components must be fitted by a qualified technician.
2. Before fitting electrical components ensure the root cause of the original failure has been addressed.
3. The absence of either of points 1 or 2 above, will void any warranty.
