A 646cc parallel twin, the BSA Golden Flash was the predecessor of the Super Rocket. It was available in black (as shown here) and chrome, but also in a gold paint scheme that led to the distinctive name. Oddly enough, the gold color (called Polychromatic Golden Beige) wasn’t an option for home-market British customers.
The Golden Flash was introduced in 1949, and was available with a rigid rear or a plunger suspension. It wasn’t designed to be a sport bike, but it was still fast compared to the competition. It could top 100 miles per hour and knock out a sub 16-second quarter mile.
This example is claimed to run ‘very good’, though it needs a voltage regulator and a battery. Find this Golden Flash for sale in Central Maine for $5,500 here on Craigslist.
