One supposes it must have been a slow year for record breaking.
The last entry is interesting. In 1935, Gnome-Rhone produced a 750cc OHV engine called the "X". In October 1937, they used this engine to establish a 24-hour world record with an average speed of 136.563 km/hour. Yacco oils were a sponsor. In July 1939, 12 French officers drove the X motorcycle 19 days and nights without stopping for an average speed of 109.38 km/hour. While the French officers busied themselves with this endeavour, German officers were occupied rather differently. As a result, two months later France declared war on Germany.
