with integrated solid state ignition
. Replaces stock 6 Volt Ldynamo L45/60L, together with regulator as well as complete magneto in the above BMW with 17mm or 20mm crank shaft. Delivers 12V/110W (ie less than standart system with single ignition). Supports dual ignition (two plugs per cylinder).  
may drive with or without battery (but check local legislation).

*NOTE: For R68 and R69 with R68 camshaft you need a different cam, please indicate at time of order.

There are two twin ignition coils in the system. One is housed in the place of the old magneto at camshaft height, the other on a holding plate under the tank. It happens that some tank tunnels are to narrow for this. There you need to fasten the 2nd coild elsewhere.
Advantages over the old system:
  • All parts are new
  • dual ignition
  • fully electronic, contactless ignition with automatic timing adjustment
  • significantly brighter light
  • no more wear on carbons, collector and governor
