And I lost track of the link to a mention of it on the zzip.de forum when I lost my internet again, but I think someone there might be able to shed some light on the subject. If we can translate it into english. OH and by the way, I saw the Super 8, I think it was a Super 8, with a CK50QT-6 somewhere.
And possibly scootergrisen may already understand what it all means. It could just be a type of "chassis code" or something for scoots like they use for a model of a car with different makes.
Gotta figure it out...
