BMW 750 Record Racer 1930
For many Germans the Ingolstadt-Munich road, with its long,
broad straightaways, was merely a pleasant, restful, and safe thoroughfare. For
BMW of Munich, on the other hand, it was the ideal place to run record-breaking
motorcycles at full speed. One of the most successful earlier models was the BMW
BMW's first attempt to beat the record that the English racer Herbert Le Vack
had set with a 1,000-cc. Brough Superior-JAP took place in 1929. The smaller
displacement of the BMW 750 did not bother the BMW's technicians. They thought
that the lower position of the engine would reduce the vehicle's resistance to
the air so that the motorcycle could outdo Le Vack's 129.06 m.p.h.
Ernst Henne, wearing a bubble helmet, rode his BMW 750 at some
135 m.p.h. on September 19, 1929. About a year later Joe Wright rode an 85-h.p.
OEC Temple-JAP 1000, with supercharger, at 137.32 m.p.h., taking the record back
to Britain again. On September 21, 1930, Henne rode a BMW substantially
identical to the one he had used in 1929 and set a new record. Henne drove the
kilometer in 16"24 at an average speed of 137.66 m.p.h.
