Bob Hall’s “Gee Bee” racers had dominated the 1931 Nationals. Behind Hall, at 237.738, was Ray Moore in the silver Rider No. 131, San Francisco I NR51Y, built by West Coast engineer Keith Rider and powered by a 6-cylinder, 160-hp Menasco in-line engine.
During a minor event in the 1931 Nationals, Moore had placed second to the Gee Bee Z and had actually beaten Wedell’s Wedell-Williams. That year, the Rider and Moore came in just 25 seconds behind Gehlbach.
It burned when the gas tank exploded on the ground in 1933. Salvage was sold to Roger Don Rae, who rebuilt it as 1934 Suzy (p: Roger Don Rae, Rudy Kling), it was a money-maker until it crashed on landing in 1936.
