Vincenzo Gambardella, of Italy

Does the background in the photo below look familiar?

The 1963 R50/2 belongs to Vincenzo Gambardella, of Italy.

Quantity of R50US Models

There is really no way of knowing how many R50US models were built. Phil Hawksley's website lists 401? meaning he doesn't really know. US models and engine numbers are included in the range of engine numbers for the R50/2. BMW did not keep separate figures for the number of models produced before 1970.

No, I did not know that. And I do not speak Italian!

However, when I was in college I did visit Rome and Florence as a tourist.

Congratulations to your site too, it's very satisfactory and well made

The second red light, which

The second red light, which is only on the late (68-69) bikes and those that have needed a replacement headlight bucket, is actually the generator light. The original, triangular red light was converted to a high beam indicator on those later bikes.

These bikes were all assembled in Munich; they are called US bikes because the "experimental" forks were only available in the US market. BMW did not sell them anywhere else, and there were apparently howls of protest at the time in their domestic market. Meanwhile, Butler & Smith, the US importer, ran ads saying that you could have your bike either way, Earles fork or telescopic.

US Models

I remember having a conversation several years ago with two older and very experienced BMW motorcycle guys who maintained that 'US' in BMW models did not stand for United States, but rather for 'Universal Strut', but I don't remember anything about which countries they were available in. Any comments from the BMW historians among us?

I'll appreciate if I could get any sort of information about my bike because I never received any answer when I wrote to andreas.harz@partner.bmw.de and today I wrote to info.grouparchiv@bmwgroup.com hoping to get answers.
many thanks

New Member with a 1969 R50us has a few questions

Hello all,
I have owned several BMW's over my 30 years of riding. I recently bought a 1969 BMW R50us in barn fresh condition, that was last registered in 1988. I replaced the tires,battery, cleaned the carbs, replaced the cables and the fluids and after kicking it for what seemed like an hour, it started! She shot out a lot of smoke and rust for the first 90 seconds but them calmed down and settled down to a nice idle. I took her out for a short ride and I was really impressed at how she sounded, rode and handled. The bike is bone stock and is a "us" model, but it has a KM speedometer which works perfectly and shows only 26000 km. My question is; did they sell "us" models in other country's?
My second question is; What is the best type and weight oil to use in the motor? I don't see an oil filter. Is there one that I am missing? does it have a serviceable debris screen that should be cleaned? Do I need to use a low or no detergent motor oil.
Any help would be appreciated.

Thank you, Henri Bock

Oil and Filters

Other than a screen in the sump and maybe a magnetic drain plug, the engine has oil slingers instead of an oil filter to get the bad stuff out. The slingers are bolted to the flywheel and can only be inspected and serviced by taking the engine down to that level. I think the service guide is to clean them at least every 30,000-50,000 miles or so. If your bike only has 26,000 km (or a little over 16,000 miles), you aren't close to that figure. But a lot of folks would check them just to know where they are at - if they get stuffed, you lose oil circulation to the crank. Not good.

With regard to oil, the consensus seems to be Valvoline VR-1 single weight. I use 40w in the summer and 30w in the winter.

Just my $0.02.

Oil thread????

I was a motorcycle wench and my parents ran a triumph dealership in the 1960's when detergent oils became popular. Those bikes were slinger cleaned and expected to use non-deturgent oil (they were dry sump though.) We were advised to NEVER change a used bike over to detergent oil as it "cleaned" the sludge from the tank, lines and sump of an engine that had run non-deturgent oil.... so.... I run 40wt non-deturgent oil and add zinc (ZDDP) that I buy for the purpose in my R60 UNTIL I get the slingers (and everything else) cleaned. This should avoid cleaning all that gunk (see Picture) and filling the slingers in a few thousand miles. Amile makes a quality 40wt non-deturgent and your local auto parts store probably has it. ZDDP can be purchased from SpamAzon.com at: http://www.amazon.com/Zddp-Maxx-Oil-Additive/dp/B003MS6QHS/ref=sr_1_2?ie...
Why worry? Get them cleaned when you can.
Ride lots... be safe

R50us steering head bearings

Hello all,
I need a little advise with 69 R50us steering head bearings. I want to convert it from the ball bearing to a tapered bearing set up. Are the bearings different on a us model with telescopic forks from a /2? Does anyone have a BCA or Federal part number so so that I can buy them from my local NAPA store? I looked around and I see that most suppliers want 100+ dollars for a set of bearings! Is there any supplier who sells them for better price? Any help would be appreciated.

Happy New Year to all
