Royal Enfield:Interceptor

NOTE: For the Triumph T120/T140 - models with a seperate inspection cover in the clutch cover. the x4 threaded bosses potrude inwards and may touch the end of the new rotor supplied. The remedy is to remove a small about of material using a 'power file', or similar grinder from the inside of the threaded boss - typically 2mm. - see images above.

NOTE: A battery is NOT required to run the ignition or lighting but advantageous for brakelight or indicators.

OPTIONAL KEY SWITCH (SW01K): Recommended when handlebar switch is not used. Switch has 2 sets of change over contacts allowing the black/white stop wire from the CDI to be connected to earth which will cut the ignition. The second set of contacts can be used to control lights - see related products below.

  • Replacement for original alternator and ignition. Complete digital self generating ignition and alternator, pre-programmed advance curve gives optimum performance for the 4 stroke twin engine.
  • No battery, contact breaker assembly or distributor required for the ignition.
  • Simple timing set-up align marks on the rotor and stator.
  • Single phase alternator 65w output with combined regulator and regulator/rectifier. This gives a controlled 12v AC output to the lighting circuit to prevent bulb failure + 12v DC output to a battery if fitted. The battery can be replaced with a capacitor pack if required, this gives greater reliability but has limited energy storage capability.
  • Most of our parts are manufactured by ourselves in the UK.
