This R75/5's story starts life in 1973. BMW UK ordered a special motorcycle, for their Golden Jubilee.
Typically, these 745cc flat twin engined motorcycles, were only available in metallic Red, Blue, or Green in the 1973 year. Therefore this bike would have been a special order in Ceylon gold, and is likely a unique motorcycle.
They then arranged to have the registration "BMW 50L" applied to the bike, BMW 50 for obvious reasons, and L - being the new 1973 registration suffix and also the Roman numeral for 50.
The bike was displayed at the Vincent square Motorcycle show, on a pedestal with a blue and white curved wall behind, that read: "1923-1973 50 Years of BMW motorcycles".
According to Roy Bacon's Book "BMW Singles and Twins", in which the bike is mentioned "and was fitted with a transistor radio made by Blaupunkt and connected to tiny speaker's in the rider's helmet. The machine was insured for £10,000"
If they sold it for the insured £10,000, it certainly must have been one of the company's most expensive motorcycle sales.
Included in the sale is a programme from the Vincent square Motorcycle show, which mentiond "Highlight of the (BMW) stand is the all-gold R75/5 marking BMW's Golden Jubilee"
Also, a copy of the February 1973 issue of "Motorcycle Sport" there is a picture of the bike on display with the aforementioned curved wall at the show, though partly obscured by an R60/5.
This bike now represents a surely unmissable opportunity for the discerning BMW collector to acquire this rare and unique motorcycle to be the pride of place in any collection.
The bike is well maintained and performs all well and as it should, it is all original and unrestored, with the exception of the fuel tank, which has been repainted.
