Lightened Charging Rotor Yamaha FZ-07/MT-07/R7 2015-Present


Spears Racing offers a way to achieve better throttle response and more torque/horsepower by machining the stock  Ignition Rotor  Yamaha FZ-07/MT-07/R7  to a special weight to achieve these kinds of results. (With Magnets)


Lighten Ignition Rotor  Yamaha FZ-07/MT-07/R7 Spears Racing offers a way to achieve better throttle response and more horsepower by machining the outer diameter of the stock FZ-07/MT-07/R7  ignition rotor to a special weight. This is a Technic that Spears Racing has been doing to Ignition Rotors since 1999. This modification will remove over .75/1 lb. of rotational mass which will present the numbers. All of the Spears rotors will be weighed /cleaned and check for spin balance. The Ignition Rotor  Yamaha FZ-07/MT-07/R7 Machined rotor will allow the engine to rev faster and allow the bike into the power at a faster rate.

The way that Spears Racing does this unit is by machining the outer diameter, we do not remove any of the OEM Magnets from the unit and this is because you can only  remove  the magnets by introducing heat to the rotor , and it is simply impossible to do this one magnet at a time, the heat introduce will soften all of the epoxy and with due time it may fail, loosing other magnets.


A core is required to complete this job, you will need to send your Original Core to use to be machined, or there will be a core fee added
