In 1972 an 11-metre (36 ft) version, the YRT, entered production as a replacement for the twin-steer Bedford VAL.

The 12-metre YNV Venturer with air suspension was the final development of the Y series, announced in 1984.

The majority were bodied as coaches, though the 8m, 10m and 11m versions were also built as single-decker buses and midibuses.

Those applicable to the Y series were as follows:[5] A further four digits or letters denoted wheelbase, transmission and body type, and the full seven-character code was incorporated in the VIN for each individual vehicle.

The Bedford Y series was sold extensively in the United Kingdom, mainly to independent operators, as well as in export markets.
