The BSA Owner's Club of Northern California is a group of enthusiasts interested in the Motorcycles of the Birmingham Small Arms company, once "The Most Popular Motorcycle in The World" as their advertising stated. Motorcycle ownership is not a requirement for membership, but encouraged as we are a riding club. With few exceptions (e.g All-British Ride, Rigid Ride) all motorcycles are welcome on our rides, but we encourage you to bring your British bike, especially BSA. You need not be a member to join us on our rides, but we hope that you will enjoy it enough to join the Club. Please check the Rides Calendar
