Yamaha R7 Race Generator Kit
THE FIRST RACE GENERATOR KIT AVAILABLE FOR THIS BIKE.
This is the complete race generator kit including the lightweight flywheel, stator, mounting plate, cup fasteners, pick-up plate, connectors and specific regulator / rectifier.
Significantly lighter than standard, offering higher output than 'race kit' versions, providing increased throttle response,less gyroscopic forces and more bhp everywhere. It is designed to fit high performance injection engines, and as a replacement for standard alternator systems.
Typical gains on a standard bike are around 4-5bhp and generally the higher the state of tune of the bike the greater the gain.
Most race kit generators have a smaller rotor with less windings running single phase in the stator so that they produce less outright power (and accordingly take less power from the crank to generate the electricity), and use a standard reg/rec.
The problem with this is that you have to rev the engine quite hard to produce any usable power and any excess electricity created is still converted to heat in the reg/rec and thrown out the back of the bike.
Our generators also use a small rotor but our windings are 3 phase and have a lot of turns of fine wire. This allows us to provide strong and consistent power at lower revs, but the clever part is in the reg/rec. The reg/rec contains a switching system which cuts the generating power when the desired voltage is reached and therefore the power is not taken from the crank to convert to unwanted electricity in the first place. This is why our reg/recs run much cooler than standard models and why you cannot use our generators with a standard reg/rec as the generator would be under load all the time creating excessive heat in the windings.
