In stock


Tri-spark’s classic twin & single cylinder ignition has NO black box and utilises 21st century technology to provide superior running and easy starting without kick back. Zero maintenance, compact and reliable. Built in self test mode and LED for setting the timing.

‘A’ version – Clockwise: The TRI-0005A is suitable for Triumph Unit Twins T100, T120, TR7RV, T140 Bonneville, Tiger, Daytona etc, Norton Atlas and 1968 Commando, Enfield Interceptor – Clockwise Rotation.

‘B’ version – Anti-clockwise: The TRI-0005B is suitable for Norton Commando 1969-75, BSA unit twins (A65, B50), BSA singles (B25 etc) and Triumph singles (Tiger Cub) – Counter Clockwise Rotation.

Why 2 versions? The direction and speed of rotation are used to optimise the starting performance which is critical for kickstarting and also helps to avoid damage to the electric start mechanism if the engine kicks against the starter. Designed to fire up easily!

The direction of rotation is the way the rotor turns when installed in the engine & viewing the front face of it.

This is a 12 volt system for positive OR negative earth/ground installations.

HT coils

Use either a pair of 6 volt coils connected in series for twins, or a Japanese dual HT coil

For single cylinder bikes use a 12 volt HT coil.

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.
