Brand new RMSTATOR Red Machined Aluminum Mosfet Regulator

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

Why use Mosfet Enhanced technology?

• Runs cooler: Runs much cooler than the traditional Shunt voltage regulator rectifier.

Polaris Sportsman 700s manufactured between 2002 and mid-2004 are plagued with recurring electrical problems. The failure of the starting system was not a matter of IF, but of WHEN it would occur.

The main problem with this reliable vehicle was the AC starter. Unfortunately, the cost of replacing the AC starter unit with a genuine Polaris DC starter unit was over $ 500 and was the only option.

Our new starter kit now converts the failing AC starting system to a highly reliable DC system for half the price of the original kit.

• Carburettor models only
• Our part is a replacement to your original unit
• Original advance curve
• Highest grade of lamination materials
• Highest grade of electronic components
• The quality is higher than OEM material
• Spark plug caps not included
• Spacer nuts included

Note:

• The RM22957 conversion kit is designed to replace the original OEM AC of Polaris, but is NOT MADE to replace the upgraded DC version of Polaris. If you have the 16 terminal CDI, (OEM #2201981) the stator corresponding to this CDI is RM01330.
• All electrical components must be fitted by a qualified technician.
• Before fitting electrical components ensure the root cause of the original failure has been addressed.
• The absence of either of points 1 or 2 above, will void any warranty.

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 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!

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

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!

Brand new Mosfet voltage regulator rectifier

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 overheat protection, rather than burn up, it will simply turn off for a while and cool off.

• Plug-and-play, direct fit, easy installation
• The quality exceeds the OEM equipment
• Improved heat sink and charging capabilities
• Higher grade of electric components

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.
• More engine power: Removes stator load resulting in more engine power.
• Optimized power: Optimize power delivery by switching the stator coils on or off.

With Enhanced Technology Design

This product is an advanced design that lowers operating temperatures for extended longevity and better performance than the OEM part.

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 overheat protection, rather than burn up, it will simply turn off for a while and cool off.

Features:

• IMPROVED & HEAVY DUTY: OEM and most SCR type voltage regulator are known to fail more than often for these vehicles. Our RMS Labs took a best selling voltage regulator and made it tougher by using highly reliable components to regulate the voltage. The result : More than 83% less failures than a standard OEM-type voltage regulator.
• RMSTATOR RENOWNED MOSFET COMPONENTS: Significantly decreases internal operating temperature with highly efficient MOSFET transistor regulation circuit. This technology runs much cooler than the OEM silicon rectifier regulation circuit and requires much less power to operate.
• AUTOMOTIVE GRADE HEAVY-DUTY CONNECTORS: Increase contact surface for distributed voltage charge on pins & less heat generated at connectors levels
• The quality exceeds the OEM equipment
• Higher grade of electric components

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.
