generator & ignition for classic 2 valve BMW /6 and /7   motorcycles
not suitable for R100 (customers report starting problems)

Please note: Larger cc BMW with older e-starter might have starting problems with our systems. The starter does not reach the needed starting revs, the engine does not start. Pushstarted it will however start. Customers with such engines should not buy our systems. For the R100 we have already excluded the R100 for exactly this problem.
Note, not for BMW with lightened flywheel, why is explained here

Special system: for BMW /6 and /7 with dual plug heads (4 spark plugs)

(base diameter 107mm - important, check!)

Magnet based generator with integrated solid state ignition. Output 12V/190W DC. Maintenance free, electronic ignition with own power supply from within the system. Replaces the stock 12V alternator (including diode plate  and  regulator) as well as all ignition parts, be it points or hall element). There is no need for changes on engine casing.

for the /5 and early /6 see system 70 67 999 00
for the R50/2 stock 12V BMW 70 64 999 00

there is a customer  video on this system on youtube

Please note!
  • does not support any existing electronic revolution counter. If you want a rev meter, have a look at our info here.
  • has only 190watts (ignition power however additional to that) and offers therefore less electric power than stock alternator
  • this is not a tuning system to get more performance. This is a replacement kit for material no longer available, simply to keep the bike running
  • the system is not suitable for BMW after the 2 valve series
advantage over original system:
  • all parts are new
  • you may technically drive without battery (but note limitations)
  • full electronic, solid state ignition
    with automatic ignition advance
  • no more wear on points, collector and governor 
  • no more trouble with damaged rectifiers
