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

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.

One mm?

The difference between 5mm and 6mm might be critical if the objective is to reproduce it.

This is complicated

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.

We have already measured 5mm

We have already measured 5mm but some people said should be 6 mm so I wonder what it should be as an original...

Clarification

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.

Jon

Explanation

Dear Miller6997,
Thanks for your clarification. My only aim is not to distrupt my bike's authenticity while fixing it. Of course I will match the numbers with the engine and also earles forks. My only aim is to make triple matching. We have this bike since 1968. This is our family bike left from my grandfa. We will be its last owner so of course I will do my best. I won't give a name but in one of a German forum site like here some people are depating the logos' measure so I want to open a topic and I want to learn what it is or what should it be ? Sone people said until 1955 it was 5mm after that time it was 6mm something like that. It was a hot topic there. So I just want to know. Thats it.
Best Regards.

I'd have to say that on my

I'd have to say that on my two pre 1970 bikes, the roundels are closer to 5mm than 6mm.
