1955 BSA GOLD STAR BACKGROUND
By 1955, the Gold Star was well-sorted and had turned into a fine machine. All Goldies were special to begin with, each engine being hand-assembled and dyno-tested at the factory. A copy of the dyno test was included with each new Gold Star. They were powerful and reliable, and they were fast, very fast. Gold Stars dominated off-road events, were highly competitive in road racing, and were a bona fide hit on the street and in showrooms. It was a major hit for BSA, both in sales and in reputation. They were produced from 1938 through 1963, a 26-year run which concluded when BSA was converting all it’s engines over to unit-construction, and Lucas stopped making magnetos. It was replaced by the unit-construction 441 Victor.

A WORK IN PROGRESS
In our efforts to complete our online index, and make this the world’s greatest website about classic British motorcycles, we’re building pages as fast as we can. The first thing we add are the pictures. Then come the specifications and then the history. So, if you see a page that just has only pictures on it, or just pictures and specs, please check back in a few weeks to see if we have it done. Thanks for your patience. And thanks for visiting Classic-British-Motorcycles.com. Please tell your friends about us.
