Another weird BMW. First look by the consultant found him saying it was a "nicely tricked out R69S with an aftermarket tank and seats."
A look at the ID plate on the neck showed it to be a far different animal. Instead of being the high compression 600cc R69S (which likely would have not been inexpensive) it was modified with external changed cylinders and valve covers. The 500 had a different stroke than the 69S. It was originally a rare 500cc R50US like the one in the post above. However, some owner had gone even wilder with the modifications and changed the US styled forks to the more common Earles fork model. On the downside was the R69S, with higher compression, needed top octane petrol versus the stock R50US.
Again, thanks to Jeff Dean, BMW vintage guru, for the details needed to sort out this Thai WTFOT BMW.
