BMW R-42 from 1926
The R42 was introduced in 1926, moved the brand more firmly down the road to profitability and success.
It was based on the R 32 but some modifications had made it faster and more practical: the brakes were improved and the engine got light alloy removable cylinder head. Braking too was improved;
Stylistically, the R32’s quaint valanced fenders gave way to simpler, more modern looking sheetmetal.
The machine was relatively light with 126 KG and the maximum speed was about 95 Km/h.
Despite the fact that all BMW two-wheelers built up to 1941 owe much to the R42, its production lasted just three years, making this model among the brand’s most desirable and sought-after vintage machines. 6900 machines were built.
