The story

A defining chapter in BSA history.

Explore the ideas, engineering and context that shaped the BSA Rocket Gold Star, then continue into its specifications and place in the marque's lineage.

Origins

By 1962 BSA had already decided the pre-unit twins were finished, and Eddie Dow, a Gold Star specialist dealer, suggested a send-off: put the tuned 646 cc Super Rocket engine into the chassis of the 500 cc Gold Star. BSA agreed, and the Rocket Gold Star was built for just two seasons.

Design and engineering

The combination worked because each half was already proven. The air-cooled twin, in Super Rocket state of tune, gave genuine performance in a light frame designed for a smaller engine, with a four-speed gearbox and chain drive. Buyers could specify touring or Clubman trim, the latter with clip-ons, rear-sets and a siamesed exhaust, and the result was one of the fastest British road bikes available at the time.

In production

Fewer than two thousand were made before production ended in 1963, and the Rocket Gold Star is now the most sought-after BSA twin by some margin — enough that convincing replicas built from A10 parts are a recognised category, and provenance matters more than condition.
