Introducing our newest Heavy Duty Flywheel Rotor For Yamaha Motorcycles
Anyone who rides or repairs a Yamaha YZF R1, FZ1 or FZ8 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 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.
A Heavy Duty Flywheel to the rescue!
New RMSTATOR heavy-duty flywheel rotor for Yamaha 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 heat and friction 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 years 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 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.

Before installing your new Stator
Check the AC output of the stator
Replace any burned or corroded connectors on stator and regulator rectifier
Check and repair any melted wiring
Use hi-temp dielectric grease on all connectors
Our stator might have a different wire color code than your original part.
All the wires are installed in the correct order; please do not change any of the wiring configurations.
This stator is designed as a direct plug-in replacement and should be used as such.
When bolting stator in, always use locking compound.
If our stator includes a pickup coil, always make sure the air gap is correct upon installation; we suggest as close as possible but no less than 0.010".
Flywheel
Before attempting to start your Yamaha motorcycle, 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".
Watch our installation video.
Warning:
Risk of electric shock. Disconnect the battery before servicing.
Ensure proper installation by a qualified technician to avoid malfunction.
