The Tri-Spark ‘Classic Twin’ digital electronic ignition is a proven drop-in system for British twins. There’s no guess work and no tuning required. It doesn’t look like an aftermarket accessory because everything fits neatly under the cap.
This unit is compatible with a wide range of 6 Volt ignition coils including dual output coils (must be long dwell type). It also features automatic dwell control for minimum battery drain and maximum spark without unnecessary heating in the coils. Electronic advance for reliable jitter free spark timing (with extra spark retard for easy kick starting and idle stabilisation).
