Hello Dears,
I want to learn about the diameter of mini Bmw stamped logos in the begining and the end of the VIN. I am talking about the bikes from 1950 until 1969. Some says 5mm and others say 6mm. What is the exact measure of it?
From Turkey
1956 Bmw R60, 1967 Bmw R60/2
Best Regards.
Looks like you have 2 bikes that fall in that time frame. What do they measure? Does 1 mm make that much difference? Just asking I dont know.
The difference between 5mm and 6mm might be critical if the objective is to reproduce it.
As Twocams asked above, why not measure the size of the logos on your own bikes? Also, I am curious to know where you can order a BMW logo stamp.
I have read about blank engine cases supplied as factory replacements, but I did not know that blank frames are available.
Members' reticence on this makes me think I'm not the only one to have alarm bells ringing in my head!!
Yasarcan,
Speaking only for myself, I think some clarification is needed here.
For most of us who own these old bikes, the issue of matching original numbers is important because it significantly affects the market value of a bike. To be clear, mismatched numbers affect the value and also make a bike ineligible to participate in most competitive judging shows. Restamping the serial number and the little BMW logos is sometimes done to make a bike look original and "authentic," even though it has been altered. We consider such an alteration to be fraudulent, and this is why we are reluctant to encourage you to stamp the frame to match the number on the engine. At the very least, the restamping should be explained to any potential new owner of the bike.
In Turkey, the situation may be quite different and these issues may be less important.

On my bike they are 5mm.

I'd have to say that on my two pre 1970 bikes, the roundels are closer to 5mm than 6mm.
Isn't there anybody knows anything about it???
