Classic Twin - Secrets Revealed!

Tri-Spark Classic Twin Secrets Revealed…..for your eyes only

We get asked all the time what makes our Tri-Spark Classic Twin ignition (for British Twins and singles) so different from the rest and I thought it was time to share that story with our customers and friends.

The problem we solved – when the engine is turning slowly and erratically during kickstarting and idling – the rotation of the crank can be difficult to predict – sparking at the wrong time can result in painful kickback, hard starting and lumpy running.

The solution – we use 2 position sensors – one dedicated for slow speed and one for normal running. By comparing the readings from these 2 sensors we get a much more detailed picture of what the engine is doing at low speed. Competitors can’t make this claim!

The result: 
  • A steadier idle
  • Easier starting without kickback – see testimonial from Brian Nicholls below
  • Smooth running throughout the rev range
  • Reduced power consumption and less heating of the coils 
More unique features

  • LED indication of static timing – extreme accuracy. 
  • Easy self-test - complete testing of the ignition system and coils without having to jump on the kick starter!
  • No black box – simple wiring, easy installation and originality maintained.
It all adds up - making your riding more enjoyable - we would love to hear your comments!


  1. Hi Steve I have had some time now to enjoy riding the Guzzi after installing the Tri-Spark ignition. I really noticed the easier starting and idle performance when cold with a much more consistent idle and an engine that appears to have a whole new lease of life throughout the rev range. Thanks again for a great product, Cheers Graeme.

  2. You say,

    "2 position sensors – one dedicated for slow speed and one for normal running."

    But, how can one sensor be for slow speed, and one for normal speed? Is one sensor designed to be more responsive at a slower rotor speed, and visa versa?

  3. Any plans for an ignition system for the BMW R60/2...?
    I have your ignition on my 70' Triumph Bonneville, and love it!!!
