The machine he rode was a 1956 BSA Gold Star Scrambler. Chuck comments, “I changed the tank to a 5 gallon, borrowed a front brake baking plate with a scoop (for additional cooling), and used a 19” front wheel instead of the standard 21” wheel preferred by the English!” The west coast distributor for BSA, Hap Alzina asked the factory for a replica of this bike. By the late 1950’s, the US market was the strongest in the world for BSA and they followed his advice and responded with the Catalina Scrambler in 1959. The machine would go unchanged until its production stopped in 1963.
