Generator Information

All our generators are supplied with the small 88mm light weight 530 grams performance flywheel.


Split Phase 40W Generator.

This is the common type found on most bike identified by yellow & white wire. Also, if your main head light only works when the engine is running, you have a split phase system.

This Generator will use the original 4 pin reg/rec from your bike.


  • Lights dim and brighten with the revs.
  • Can’t install LED lights.
  • Can't operate LCD clocks with out them failing in time.



  • Yellow wire = A/C out to reg/rec & head light switch
  • White wire = A/C out to reg/rec battery charging
  • Green = Earth
  • Black/Red = Source coil
  • Blue/white = Trigger


Single phase 40W Generator.

This is the type of system where all the electrical components run off a battery. Identified by having 2 yellow wires.

Safe to run LED lights & LCD display and the lights don’t dim and brighten with the engine rev’s

Comes suplied with correct type RR reg/rec


  • 2 X Yellow wire = A/C out to reg/rec
  • Green = Earth
  • Black/Red = Source coil
  • Blue/white = Trigger


Three phase 100W Generator

Same as the single phase 40W Generator but with a much higher output.

You can run better light such as a 55W head light and other additional accessories.

You will need the 4 pin CDI option for this to work, it’s a simple conversion this we can run though if you email us.


  • 3 X Yellow wire = A/C out to reg/rec
  • Blue/white = Trigger


Race generator. No Lights.

This system runs only the ignition only. There is no lighting coils and hence, will not run  lights.

4 source coils supply the CDI rather than 2. Due to no lighting coils, this reduces fluxing and resistance.

  • Black/red = Source coil CDI power
  • Blue/white = Trigger coil
  • Green = Earth
