Description
1964 BSA A65SH Hornet Flat Track Racer – Period-Correct A65 Engine in Lightweight A50 Star Frame
Ultra-Rare US-Market Scrambler Hybrid: ~1, 500 Hornets Built, Fewer with This Proven Racer SetupThe Build: A Piece of 1960s West Coast Dirt Track History
Engine: A65H338 – Genuine 1964 Hornet 650cc parallel-twin (42 hp @ 6, 800 rpm), delivering the torque that powered BSA's Trackmaster wins against Harleys on ovals and miles.
Frame: A50C15001 – 1964 A50 Star chassis (500cc origins), chosen for its lighter weight and agile handling— a classic period swap for superior power-to-weight in flat track and scrambles.
99% Correct to Era Spec: High pipes, knobby tires, no lights; 80% original components (paint, tank, seat) with authentic race patina. Mirrors successful '60s builds where A65/ A50 hybrids ruled AMA circuits post-rule changes favoring BSA's punchy unit-construction twins.
Starts & Runs: Recently fired up after 30+ years of dry California garage storage—leaks oil like a proper Brit (fixable with fresh gaskets). Ready for light recommissioning, AHRMA vintage racing, or display.
