I added a 2003 CDI to my 2002 640 and placed a switch on the dash so I could switch between high and low octane fuel.
I ran it on 80 octane with no problems, but big throttle openings on 76 octane fuel would make it ping.
with the CDI on the high octane setting the lowest fuel I could run without inducing pinging was 92 octane.
Petrol/gas does vary from place to place. My Honda transalp seems to run on anything down to 85 octane without any problems, apart from loss of power.
The KTM part number for the CDI box was.. 58439031300 I think it cost around 200 euros.
