1950s BSA Gold Star Valuation Report

Date: August 2025

Historical Overview

The BSA Gold Star was one of the most iconic British motorcycles of the 1950s, renowned for its performance in club racing, the Isle of Man TT, and scrambles. Produced in both 350cc (DB32) and 500cc (DBD34) configurations, it featured a high-compression single-cylinder engine, lightweight frame, and distinctive alloy tank. In the UK today, it remains one of the most sought-after classic singles, with top examples commanding strong auction results.

• Market Trends: UK Gold Star prices are strongest in spring and pre-vintage race seasons.
