Electrex World STK-106 Digital CDI Ignition Kit – Norton Commando, Atlas, BSA A50/A65, Royal Enfield Interceptor (Twins)

Electrex STK-106 digital ignition kit – Electrex World STK-106 digital ignition Norton Commando — the Electrex World STK-106 is a complete digital CDI ignition kit for classic British twins — a direct replacement for the original contact breaker points and mechanical advance unit. Fits Norton Commando, Norton Atlas, Norton Dominator, BSA A50, BSA A65, and Royal Enfield Interceptor.

Designed and manufactured in the UK by Electrex World, this self-contained kit uses a Hall effect trigger and pulsar ring system to deliver a precise, electronically controlled spark with no moving parts to wear out. The CDI (Capacitor Discharge Ignition) system produces a very high HT voltage — up to 40kV — with an extremely short spark duration for clean, efficient combustion. Current consumption is very low compared to conventional 12V electronic ignition kits.

Setup is straightforward: the pulsar ring is engraved with degree markings for easy timing with the piston at TDC, and an LED on the pulsar ring indicates both the point at which the spark fires and the presence of a suitable power supply — making initial setup and troubleshooting simple.
