Introducing the newest Heavy Duty Flywheel Rotor for Aprilia Motorcycles.
Anyone who rides or repairs Aprilia Motorcycles is probably familiar with the flywheel problems common to these models. Most of these machines will have at least one flywheel failure in their lifetime so far. 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 Aprilia flywheels to save the $400+ OEM replacement. This sounds like a great idea at first, but there are some serious issues!
The common repair is using JB Weld© Marine Blue Epoxy to reattach the loose original magnets, or to install new ones. Epoxy fixes do repair flywheels in the short term if they are done correctly. However, this kind of repair can easily cause immediate problems and impact the long-term reliability of the motorcycle.
A Heavy Duty Flywheel to the rescue!
New RMSTATOR heavy-duty flywheel rotor for Aprilia Motorcycles is a well-priced solution to problems with the OEM flywheel, and an excellent alternative to all the mechanical troubles you can encounter with a repair.
Features:
-
Built to OEM size
Fits precisely in the 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
Two-year warranty. All products are tested.
Why cheap repairs won't work?
Quick, stronger epoxy fixes do repair flywheels in the short term. It might, however, impair long-term performance and reliability of the 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 the broken flywheel with a new $400+ OEM one or the new heavy-duty flywheel.
Before attempting to start the Aprilia, 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".
Warning:
Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
