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.

  • 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 the 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.

Why use Mosfet Enhanced technology?

  • Runs cooler - Runs much cooler than the traditional Shunt voltage regulator rectifier.
  • 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.

With Enhance Technology design

This product is an advanced design that lowers operating temperatures for extended longevity and better performance than the OEM part.

Brand new Mosfet voltage regulator rectifier

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.

  • Direct replacement to your original unit
  • Plug-and-play, direct fit, easy installation
  • The quality exceeds the OEM part
  • Higher grade of electric components

Opposite connector (main harness side) included as we know these are often melted/corroded/defective and a major cause for repetitive electrical issues.

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 a 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.

PLEASE NOTE: This voltage regulator is ONLY for lithium batteries THIS IS NOT FOR LEAD ACID BATTERIES. Output Voltage is the key factor in a voltage regulator designed specifically for Lithium batteries. The ideal charging voltage for Lithium batteries is 13.9-14.2VDC. The RMSTATOR regulator has a carefully set output voltage of 14.1VDC (+/- 0.1VDC). This stable and ideal output voltage carefully keeps a lithium battery in its ideal charging range.

Please Note:

  1. All electrical components must be fitted by a qualified technician.
  2. Before fitting electrical components ensure the root cause of the original failure has been addressed.
  3. The absence of either of points 1 or 2 above, will void any warranty.

Love love love Robeez. Best soft soled shoes for baby/toddler just learning to walk.
Size: 12-18 Months Toddler, Color: Grey Leather
I can’t even tell you how much I love these shoes for my kids. My oldest son born 2018 had a pair of Robeez, the shark kind, and I’ve passed them down through all my boys until now- now somehow one of them has gone missing, still looking. So we got these for baby and oh my gosh Robeez has upped their game! The soles are still soft enough to be pliable but have some structure to them, they fit softly enough to accommodate round chubby feet but again have some structure, and they look adorable. The quality is really high and that’s so wonderful to see this day and age when so many things are produced cheaply. These are truly lovely. And they’re very handsome. My sweet boy wore them to a birthday party at the park and they were a hit. I love this brand so much, and these shoes are so cute. I wish I were having more kids to buy more cute pairs :)

The Perfect First Shoe! Worth the Price.
My little one was just starting the stand/learning to walk and we wanted something to protect his feet while we were out of the house. Since babies/toddlers grow out of their shoes so quickly, I tried desperately to find shoes that didn't cost more than $20. However, I tried about 6 different "cheaper" shoes, all different brands, and nothing would stay on my babies feet. I finally broke down and bought these shoes and they are perfect. I ended up wasting more money trying not to spend too much money on shoes that would be too small after a couple months. It would have been cheaper for me to just buy these shoes to start. Fit wise they are great. Super easy to put on. They stay on! I appreciate the rubber portion on the sole because it gave my little one more traction when he was learning to walk. They are light way and the sole is very flexible which is important for the proper development of their feet. I just wish they made larger sizes because I am going to have to start the hunt all over for the perfect shoe once he grows out of the biggest size that Robeez sells. Save yourself time and avoid wasting money on shoes that don't stay on. Just buy these shoes!

Cute and STABLE
Size: 12-18 Months Toddler, Color: Navy Leather
This brand was recommended by a family member as being good for kids who are learning how to walk, and I definitely agree. My son had a different pair of shoes from Carter’s that fit well and looked cute, but the soles were a little too slick for an early walker despite having little rubberized dots on them. I like that these have more realistic soles, with real traction and support, but still allow the kid’s foot to flex. My son is very comfortable in them and was immediately noticeably more stable while standing and practicing walking in them. Bonus- they are super cute and this design is neutral enough to go with plenty of his clothes. My only small complaint is a little thread coming loose on one shoe, but so far it isn’t causing any issues/doesn’t seem to be unraveling anything structural. Highly recommend overall!
