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 wasn’t an option in 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 bike has a rebuilt engine and it’s been converted to a 12V electrical system. Extras include a windshield, leather saddle bags, turn signals, and the parts/repair manuals. Find this BSA Golden Flash for sale here on Craigslist in Plymouth, Michigan for $5,500.
