Race Ignition Kit Fits:

BSA:Bantam Trials D10

High energy self generating cdi ignition system (sparking starts at 250rpm), located in place of the original Wipac alternator in the left hand cover - Single Spark Plug System.

  • Replaces the original Lucas/Wipac alternator and rotor. Points, distributor and battery are not required.
  • The spark energy and the timing are produced by the stator coil. The exact advance curve is determined by the stator + CDI combination.
  • Connects directly to the CDI unit, and HT coil.
  • Additional weight (approx 1/2kilo) is available for added momentum. Bolts directly onto the rotor. Electroplated for corrosion reduction.
  • Kit comes with the appropriate screws and spaces but you may also purchase from us an extractor and rotor holder.
  • Keyless rotor fitting on to crankshaft. This uses a larger collet to lock the rotor key securely onto the crank. Advantages over a woodruff key and keyway are infinite repositioning of the rotor for ignition timing, can be used on a worn crank or damaged keyway.
  • Manufactured in the UK.

Optional weight available
High quality electro plated weight can be attached with x2 M6 screws to the engine side of the rotor, weighs 578g - see related products below.

In common with other suppliers we are unable to offer warranty for electrical components used for racing.
