The BMW R68 is a marvel of motorcycle design, introduced in 1952 as the “100 mph motorcycle.” This road and cross-country variant boasts a robust engine, with a raised compression ratio of 7.7:1 and larger 26mm Bing carburetors, providing a potent punch for its time.
The R68’s engine character is unmistakable, with a rich, flat sound produced by its unique silencer system. The cross-country version’s single-fin silencer, with twin pipes crossing over the top of the engine, adds to its distinctive profile.
Riding the R68 is an exhilarating experience, with its telescopic front fork and plunger-type spring providing a smooth ride. The rear main bearing’s fully floating design allows for a hint of crankshaft flexibility, making it a joy to navigate twisties.
The BMW R68 is a testament to the brand’s commitment to innovation and performance, with a rich history that spans over five decades.
