Offset Crank Rotor Modification for Classic Twin Ignition

The Classic Twin is generally used for parallel twins with a 360-degree crank configuration, however it may be used with 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 specify the degrees and for what bike when ordering, via email and in the delivery note section.

We recommend using a 12-Volt Dual Lead Ignition Coil with an offset crank.

DOES NOT INCLUDE THE ROTOR.  THIS IS A MODIFICATION TO THE ROTOR SUPPLIED WITH A CLASSIC TWIN IGNITION.

If you wish to purchase a Classic Twin ignition rotor separately add a Spare Part Classic Twin Rotor to your cart along with the offset crank modification.
