The 2004-2009 Aprilia RSV and Tuono models are excellent motorcycles, but all suffered from a very unreliable charging system. The issue was an extremely strong magnetic flywheel that caused excess heat in the stator windings and common repeat failures. A replacement stator of the original design was simply not a reliable solution. The high output from the stator also caused regular voltage regulator failures, making for a very poor charging system.

To solve this problem, RMSTATOR has engineered a permanent solution kit to address all parts of the charging system. A thinner stator core is used that generates and retains less heat in use, and promotes cooling due to increased oil coverage from the extra space inside the flywheel. Paired with a MOSFET type voltage regulator compatible with lithium-ion batteries, the charging system is now bulletproof. For a complete and easy installation, we include shorter stator mounting bolts, a plug & play adapter harness for the new voltage regulator, and a stator cover gasket.

Lithium-ion Compatible Regulator

WORKS WITH LITHIUM BATTERIES ONLY

Stop burning your voltage regulator rectifier!
It is time to update or replace your voltage regulator with the advanced MOSFET type.

It runs cooler than all SCR diode-style OEM 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 part
• Higher grade of electric components

Why do you need a different voltage regulator for lithium batteries?

Lithium batteries have different charging requirements than Lead Acid or AGM batteries that can severely affect their lifespan and performance. The key factors in safe and reliable lithium battery charging are the output DC voltage ripple and average output voltage. The RMSTATOR regulator is designed around the optimal parameters for these factors.

The ripple effect is all that matters

Charging voltage ripple in a powersports application is the difference between the highest and lowest voltages from the voltage regulator output. By nature, a common shunt style voltage regulator will have a fairly high voltage ripple due to the regulation shunt switches opening and closing frequently. Each on/off transition will cause some variation in the output voltage, this is unavoidable. Keeping this to minimum is critical for Lithium batteries, and the RMSTATOR Lithium regulator is designed around this feature.

In a perfect world, a ripple of less than 10% of the output voltage (~1.5V for a typical regulator), would be ideal, however is not practical for this type of regulator. The RMSTATOR Lithium regulator is able to maintain a less than 4 Volts output ripple, compared to verified test results of our competitors 8 volts. Keep in mind this ripple voltage is only seen via an Oscilloscope sampling the voltage 1000’s of times a second, and is not the same as your average charging voltage as measured by a multimeter.

Why use Mosfet Enhanced technology?

Runs cooler

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.
