Two versions

  • The 'A' type is for engines where the Tri-Spark trigger rotor turns CLOCKWISE (Triumph unit twins, Norton Atlas, 1968 Commando, RE intercepter, Velocette)
  • The 'B' type is for engines where the trigger rotor turns COUNTER CLOCKWISE (Norton Commando 1969-75, BSA A65, BSA unit twins and singles, Triumph singles, Tiger Cub)

The direction is the way the Tri-Spark rotor turns when installed in the engine and looking at the front face of the rotor.

Why 2 versions? The direction and speed of rotation are used to opimise the starting performance which is critical for kickstarting and also helps to avoid damage to the electric start mechanism which is easily damaged in some machines if the engine kicks against the starter. We designed this unique system because want your engine to fire up easily!

Classic Twin for offset crank

The Classic Twin is generally used for parallel twins with a 360-degree crank configuration, however it may be used on engines with offset cranks such as 270-degree.  A modification is required to the trigger rotor for offset crank applications to reposition the magnets to suit your engine.  Please add the Offset Crank Rotor to your cart and specify the degrees and for what bike in the delivery note section.
