Improved Magneto Flywheel Rotor for Yamaha YZF R1 / FZ1 1000 / FZ1-N FAZER / FZ8 800 / FZ8-N FAZER8 2004-2015

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!

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.

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.
