Replace like a pro! New Heavy Duty Flywheel Rotor Aprilia 1000cc Motorcycle Introducing our newest Heavy Duty Flywheel Rotor For Aprilia 1000cc Motorcycles. Anyone who rides or repairs Aprilia 1000cc 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 short term, if they are done correctly. However, this kind of repair can easily cause immediate problems, and impact long term reliability of your Motorcycle. Watch Evan, our head of engineering, explaining why you must not repair a flywheel. A Heavy Duty Flywheel to the rescue! New RMSTATOR heavy-duty flywheel rotor for Aprilia 1000cc 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 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 Two year warranty. All products are tested. Don't waste time with temporary solutions, and start fixing your ride like a pro! 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 damages. 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 a new 400+ OEM one or our new heavy duty flywheel.
