A Point Loma, San Diego chapter of the Antique Motorcycle Club of America, San Diego Antique Motorcycle operates from 1273 Scott Street near the Shelter Island marina district. The club's preservation mission aligns with the vintage-parts sourcing and period-correct rebuilds handled at nearby Citywide Cycles Harley Repair, where pre-war and post-war machines receive matching-numbers engine work. As a non-profit mutual-benefit corporation, the organization sponsors antique motorcycle rides, judged exhibitions, and swap meets that draw collectors from across Southern California. Members maintain marques spanning early Harley-Davidson flatheads, Indian Chiefs, BSA singles, and Triumph Bonnevilles, with hands-on technical sessions covering magneto ignition rebuilds and spoke-lacing clinics. General mechanical support for members' street-use bikes and tow vehicles routes through Rosecrans Automotive on the Point Loma peninsula. The most involved restoration projects take a bare frame through complete powder-coating, chrome re-plating, engine machining, and concours-level reassembly for AMCA national judging.
