A last-ditch 350 cc double-overhead-cam parallel twin that BSA hoped would take on the Japanese lightweights in 1971. It shared its design with the Triumph Bandit and drew on the frame of the racing triples. The group's financial collapse killed it before production, leaving only a handful of prototypes.
