Hello,

We are in the process of brokering the purchase of this bike: http://motosantiguashd.com/en/index/moto/bmw-r-12-1938-2/

My questions are:

The numbers are not matching, what would pricing be?
The seller does not have documents except for a bill of sale. Does this create problems with US customs?
Has anybody done business with this company before?

Any other information regarding this bike would be appriciated.

Thank you,

Marc Beyer

The engine and frame numbers

The engine and frame numbers on a 1938 R12 wouldn't normally be the same, but BMW can probably tell you if the engine and frame left the factory together. Send an email with the numbers to info.grouparchiv@bmwgroup.com.

Regarding the photos, I see that the tubes for the carb heater are missing. They have a hollow flange that fits between the exhaust port and the header, and a tube that then runs up to cast induction tube, where you can see the open holes. Because of the missing flange, there are spacers added to the header mounting studs on the cylinder.

There are two different style heads mounted. The right side is the wartime style, with its cast in OZ-74 marking (indicating that the vehicle runs on 74 octane gas). The left side is an earlier head without this marking. Both are missing the one (early) or two (late) small vertical supporting ribs that would normally come up to meet the bottom horizontal rib.

Along with the right head, this bike has a lot of other wartime parts on it. For example, the aluminum strap holding the magneto; earlier straps are made from a special alloy, zamak, that looks like brass. The gas tank has the large cap and opening supplied to the military. The top fork covers with the headlight ears are wartime items, made from sheet metal; the civilian covers are cast aluminum. The front fender is also a wartime part with the exposed supporting strap over the fender sheet metal. The speedometer has the wartime face. BTW, the hand painted number just above the odometer beginning with 34..., if it is correct, indicates a late 1941 serial number. And the driveshaft is the wartime version with the locking nuts at the front.

Other things I see: the horn is wrong for the bike. The key switch in the headlight shell is a replacement that indicates the shell has been modified internally, if it isn't a reproduction item. The latter is quite likely as the hole that would normally take the 8 amp torpedo fuse instead has a generator light lens mounted. Unfortunately, the stock magneto doesn't provide a way of powering a generator light. The reproduction headlight glass is mounted upside down and the acorn nut holding the knob on the shift lever looks ridiculous.

Correction

The alloy used for the magneto strap is not zamak, but tombak (also, tombac).
