Boyer Bransden 12V MarkIV Ignition System for Norton Atlas or Commando

Boyer Bransden produces one of the most efficient ignition systems in the world.  All systems are carefully hand built in the UK.  Electronic ignition is now standard for the majority of new motorcycles. It offers better starting, smoother running, improved fuel economy and lower emissions when compared with more traditional systems.

On certain types of older or high mileage motorcycles, wear in the distributor may affect the timing and cause a falling away of performance, leading to sparking at the points, and burning of the contacts that wastes energy.  Some classic motorcycles suffer from "fragile" electrics which may be affected by vibration or dampness; often an electronic ignition system will eliminate these problems allowing the machine to be used with greater confidence and to its full potential.
