What is a charging flywheel?

A charging Flywheel is a billet aluminum replacement for the stock steel flywheel. Since the stock versions are generally very heavy, they require a large amount of horsepower to overcome their weight and this substantially reduces the engine’s ability to respond to throttle movements. The patented Jetinetics Charging Flywheel is significantly lighter, 50% in some cases, which greatly reduces the energy used to overcome flywheel mass and allow the engine to increase rpm’s rapidly. A significant benefit is the fact that the engine will produce horsepower only after it has reached it’s powerband which usually begins around 3800 rpm. By using a Jetinetics Charging Flywheel, the engine is able to reach it’s powerband much more quickly and create usable power much sooner. Further, during rapid cornering such as course racing or slalom runs, this becomes a significant factor for acceleration.

 

How does it work

Put quite simply, a flywheel is a rotor which supports a ring gear for starting, and magnets which are used to electrically charge both a (capacitor discharge ignition) and the on board battery. The Jetinetics Charging Flywheel uses aluminum as the basis for the rotor, specially designed high temperature magnets, and a tough, alloy steel ring gear to reproduce all aspects of the stock assembly. The rotor is started turning by the starter motor, then the magnets create electrical energy to fire the ignition and charge the battery.

 Jetinetics is the originator of the charging aluminum flywheel, and proudly retains the manufacturing right to its patented designs. Any other charging flywheel is nothing more than a copy of the original!
