[3][4] Prince, an Englishman, had emigrated to the United States after the end of his racing career and developed a thriving business building velodromes.

[3] By 1909, Prince had built the Los Angeles Coliseum Motordrome, a velodrome-like motorcycle racing facility that was just over 1⁄4 mile (0.40 km) in circumference.

[5] Around the time that Moskovics' career brought him to Los Angeles, in 1909, Carl Fisher was developing the Indianapolis Motor Speedway, and automobile racing was gaining momentum as a business.

[7][8][9] Construction began on January 31, 1910 and was scheduled for just 25 days to complete the racing surface and another 30 to build the grandstands and the rest of the facilities.

[3] While the racing facilities were being built, Pacific Electric Railway constructed a special 3⁄4-mile (1.2 km) track spur to deliver spectators via Red Car trolley.

[17] Notable racers Barney Oldfield, Ralph DePalma, Lewis Strang, Ray Harroun, Joe Nikrent, and Caleb Bragg were all in attendance.

[4] The Motordrome's promoters had promised that world records would fall at the new race track, and efforts were made to deliver as quickly as possible.

[22] In May of that same year, "Texas Cyclone" Eddie Hasha set a new 1-mile (1.6 km) motorcycle record at the Motordrome, reaching 95 miles per hour (153 km/h).

[4] That record fell in December 1912 to Lee Humiston, who broke 100 miles per hour (160 km/h) while riding an Excelsior, a speed never reached or bested by any of the automobiles.
