He worked for leading UK marques including JAP, Ariel, Triumph, and BSA.

[3] Page was an innovator whose radical designs include the Triumph 6/1; BSA Gold Star, M20, and A7; Ariel Leader; and the JAP engine of the Brough Superior SS100.

[5] Page's designs formed the basis for what became the Red Hunter, which continued until Ariel ceased production of four-strokes in 1959.

His designs included the Empire Star, which was developed into the high performance production BSA Gold Star, named in celebration of Wal Handley's 100 mph lap time at the Brooklands circuit.

[citation needed] The innovative Gold Star had a single cylinder 500 cc engine with twin pushrods operating double-coil springs and overhead valves.
